765519ea92 drivers/sensor: fix some ST drivers dependency to HAL_ST module
In order to avoid build failures as described in issue #67242,
make all ST drivers using HAL_ST module dependent to HAL_STMEMSC
and HAS_STLIB libs, which need to be configured in all samples
referring to them.

df81fef944 drivers: sensor: Convert Kconfig bus 'depends on' to 'select'
This change in pattern is meant to address a misconfiguration issue
that can occur for sensors that support being on multiple busses
like I2C & SPI.

For example, you can have a configuration in which such a sensor is
on the I2C bus in the devicetree and the sensor is enabled.  However
the application configuration enables CONFIG_SPI=y and CONFIG_I2C=n
and this will cause the sensor driver to be built by default, however
since we don't have the I2C bus enabled the driver will not compile
correctly.

Previously we had been adding to board Kconfig.defconfig something
like:

	config I2C
		default y if SENSOR

This pattern doesn't scale well and may differ from what an application
specific need/use is.

So instead move to a pattern in which we leave the default enablement
up to the devicetree "status" property for the sensor.  We then have
the Kconfig move from 'depends on <BUS>' to 'select <BUS>' and in
the case of drivers that support multiple busses we have the Kconfig
be: 'select <BUS> if $(dt_compat_on_bus,$(<DT_COMPAT>),<BUS>) for
each bus type the sensor supports.

This removes the need to add Kconfig logic to each board and enables
the bus subsystem and bus controller driver if the sensor requires
it by default in the build system.

Fixes: #48518

93d06330c5 drivers: sensor: vl53l0x: add support to reprogram I2C address
The I2C address of the VL53L0X distance sensor can only be programmed
over the I2C bus. To do this:

1. The sensor is powered off or in standby mode
2. Power up the sensor, it boots with a default I2C address (0x29)
3. The I2C master sends a configuration command to set the new address
4. The sensor now communicates at the new address

In case there are more than one such sensor on the bus, they all have
the same address when starting up. We therefore need to first apply
step 1. on all of them. Then, sensor by sensor apply steps 2. to 4.

Because simple designs may not need to reprogram the address, we
introduce a new configuration option CONFIG_VL53L0X_RECONFIGURE_ADDRESS

If this setting is disabled, then the driver behaves as before.

If CONFIG_VL53L0X_RECONFIGURE_ADDRESS is enabled, then the driver does
the following:

- In vl53l0x_init(), apply step 1. This is done when the driver is
  brought up when starting the system
- in vl53l0x_start(), apply steps 2. to 4. This is done when fetching
  a sample, if the sensor has not been started yet.

Also, as cosmetic changes:
- add parenthesis around sub conditions in call to __ASSERT_NO_MSG
- gracefully handle unknown sensor channels in vl53l0x_channel_get

eddd98f811 kconfig: Replace some single-symbol 'if's with 'depends on'
I think people might be reading differences into 'if' and 'depends on'
that aren't there, like maybe 'if' being needed to "hide" a symbol,
while 'depends on' just adds a dependency.

There are no differences between 'if' and 'depends on'. 'if' is just a
shorthand for 'depends on'. They work the same when it comes to creating
implicit menus too.

The way symbols get "hidden" is through their dependencies not being
satisfied ('if'/'depends on' get copied up as a dependency on the
prompt).

Since 'if' and 'depends on' are the same, an 'if' with just a single
symbol in it can be replaced with a 'depends on'. IMO, it's best to
avoid 'if' there as a style choice too, because it confuses people into
thinking there's deep Kconfig magic going on that requires 'if'.

Going for 'depends on' can also remove some nested 'if's, which
generates nicer symbol information and docs, because nested 'if's really
are so simple/dumb that they just add the dependencies from both 'if's
to all symbols within.

Replace a bunch of single-symbol 'if's with 'depends on' to despam the
Kconfig files a bit and make it clearer how things work. Also do some
other minor related dependency refactoring.

The replacement isn't complete. Will fix up the rest later. Splitting it
a bit to make it more manageable.

(Everything above is true for choices, menus, and comments as well.)

Detected by tweaking the Kconfiglib parsing code. It's impossible to
detect after parsing, because 'if' turns into 'depends on'.

bd6e04411e kconfig: Clean up header comments and make them consistent
Use this short header style in all Kconfig files:

    ...

Also change all <description>s from

to just

    # Foo-related options

It's clear enough that it's about Kconfig.

The <description> cleanup was done with this command, along with some
manual cleanup (big letter at the start, etc.)

8cf8db3a73 Kconfig: Use a short, consistent style for prompts
Consistently use

    config FOO
            bool/int/hex/string "Prompt text"

instead of

    config FOO
            bool/int/hex/string
            prompt "Prompt text"

(...and a bunch of other variations that e.g. swapped the order of the
type and the 'prompt', or put other properties between them).

The shorthand is fully equivalent to using 'prompt'. It saves lines and
avoids tricking people into thinking there is some semantic difference.

Most of the grunt work was done by a modified version of
https://unix.stackexchange.com/questions/26284/
how-can-i-use-sed-to-replace-a-multi-line-string/26290#26290, but some
of the rarer variations had to be converted manually.

Bool symbols implicitly default to 'n'.

A 'default n' can make sense e.g. in a Kconfig.defconfig file, if you
want to override a 'default y' on the base definition of the symbol. It
isn't used like that on any of these symbols though.
