This configure and connect host /dev/pts/N to arm qemu uart-1. It can
use a real device like /dev/ttyS0. Just switch config between serial
and pty chardev options.
In addition, this update QEMU_EXTRA_FLAGS to use only variables instead
hard coded values.

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

Up until now, the vl53l0x driver only supported a single device, ie.
the first entry st,vl53l0x in the device tree. To be able to use
multiple sensors at the same time, create one driver data instance per
vl53l0x node in the device tree. Also split the constant driver config
from the runtime data.
Because the vl53l0x address is only configurable with an I2C command,
and is not persisted if the sensor is rebooted, multiple sensors can
be handled only if either:
- They are on different I2C buses
- Their addresses are coonfigured (by some external code) before
vl53l0x_init is called
Also use the i2c_dt_spec and gpio_dt_spec APIs, as it makes
the code more concise and readable.
Finally, to distinguish the logs mesages from different sensors,
prefix the text with the sensor name.

As per the VL53L0X datasheet, in 2.9.1 "Power up and boot sequence",
time to boot is 1.2ms max, so we only have to wait at most 2ms.

Don't autoconnect EATT as this was confusing PTS and resulted in
multiple tests failures. When needed PTS will connect EATT bearer.

Add soc_secure_mem_read implementation for secure.
This simplifies users code so that ifdefs are not required.

The limitation on HWINFO_NRF depending on not nonsecure was removed in
52be3030aa.
This caused problems when TF-M was not enabled.
This happens on the thingy53_nrf5340_cpuapp_ns board since this board
is not supported by TF-M.
Introduce proper dependency handling for the soc secure functions
to make HWINFO_NRF unavailable when no secure services exist in
nonsecure.
