When the STM32L4x SoC goes into STOP mode, the SPI device is disabled.
This cause the pins to not be drived anymore (i.e. they are floating)
except through their pull-up or pull-down.
From the logical point of view, the NSS pin is held high by a pull-up
so it's not a problem if the other pins are floating. However those pins
are floating input for the slaves, which increase their power
consumption.
The solution is to hold the state of the pins through a pull-up or a
pull-down. This is already done for the NSS and MOSI pins, but not for
SCK. Fix that by using pull-down on the SCK pin the same way it is
already done for the MOSI pin.

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'.

Ensure that the SPI SCK and MOSI pins are set to very high as slower
SPI speeds will cause device hangs when used. This is due to the state
changing too fast for hardware, causing RXE to never fire and thus
hang.

Use this short header style in all Kconfig files:
# <description>
# <copyright>
# <license>
...
Also change all <description>s from
# Kconfig[.extension] - Foo-related options
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.)

Clean up space errors and use a consistent style throughout the Kconfig
files. This makes reading the Kconfig files more distraction-free, helps
with grepping, and encourages the same style getting copied around
everywhere (meaning another pass hopefully won't be needed).
Go for the most common style:
- Indent properties with a single tab, including for choices.
Properties on choices work exactly the same syntactically as
properties on symbols, so not sure how the no-indentation thing
happened.
- Indent help texts with a tab followed by two spaces
- Put a space between 'config' and the symbol name, not a tab. This
also helps when grepping for definitions.
- Do '# A comment' instead of '#A comment'
I tweaked Kconfiglib a bit to find most of the stuff.
Some help texts were reflowed to 79 columns with 'gq' in Vim as well,
though not all, because I was afraid I'd accidentally mess up
formatting.

Defining a symbol with 'menuconfig' just tells the menuconfig to display
any dependent symbols that immediately follow it in a separate menu.
'menuconfig' has no effect on symbol values.
Making a symbol that doesn't have any dependent symbols after it a
'menuconfig' should be avoided, because then you end up with an empty
menu, which is shown as e.g.
[*] Enable foo ---
This is how it would be shown if there were children but they all
happened to be invisible as well.
With a regular 'config', it turns into
[*] Enable foo
Change all pointless 'menuconfig's to 'config's.
See the section on 'menuconfig' on the Kconfig - Tips and Best Practices
page as well.

To work efficiently, SPI_NSS pins require pull-up configuration.

Fixes#17998
Signed-off-by: Erwan Gouriou <erwan.gouriou@linaro.org>
Fixes#16739. Changed the STM32's SPI MISO/MOSI configurations in order
to reduce the power consumption by approximately 20uA per pin.
According to STM32's Application Notes on GPIO configuration for
low-power consumption, the input pins should be configured with internal
pull-up or pull-down resistor. If a pin is configured as a floating
input, and there is no signal present, the Schmitt trigger randomly
toggles between the logical levels induced by the external noise, thus
increasing the consumption.
