Kumar Gala 31dad5b411 sensor: vl53l0x: Convert to new DT_<COMPAT>_<INSTANCE> defines
Convert vl53l0x sensor driver to use new defines so we can remove the
dts_fixup.h code for it.

Himanshu Jha f411073c85 drivers: sensor: vl53l0x: remove unnecessary variable
Remove an unnecessary local variable to store the
return value, instead return directly thereby saving
few bits of memory.

Found using Coccinelle.

Andrzej Głąbek 20202902f2 dts_fixups: Use DT_ prefix in all defined labels not related to Kconfig
These changes were obtained by running a script  created by
Ulf Magnusson <Ulf.Magnusson@nordicsemi.no> for the following
specification:

1. Read the contents of all dts_fixup.h files in Zephyr
2. Check the left-hand side of the #define macros (i.e. the X in
   #define X Y)
3. Check if that name is also the name of a Kconfig option
   3.a If it is, then do nothing
   3.b If it is not, then replace CONFIG_ with DT_ or add DT_ if it
       has neither of these two prefixes
4. Replace the use of the changed #define in the code itself
   (.c, .h, .ld)

Additionally, some tweaks had to be added to this script to catch some
of the macros used in the code in a parameterized form, e.g.:
- CONFIG_GPIO_STM32_GPIO##__SUFFIX##_BASE_ADDRESS
- CONFIG_UART_##idx##_TX_PIN
- I2C_SBCON_##_num##_BASE_ADDR
and to prevent adding DT_ prefix to the following symbols:
- FLASH_START
- FLASH_SIZE
- SRAM_START
- SRAM_SIZE
- _ROM_ADDR
- _ROM_SIZE
- _RAM_ADDR
- _RAM_SIZE
which are surprisingly also defined in some dts_fixup.h files.

Finally, some manual corrections had to be done as well:
- name##_IRQ -> DT_##name##_IRQ in uart_stm32.c

Ulf Magnusson 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.

Ulf Magnusson 19d7803546 drivers: sensor: Kconfig: Remove redundant 'default n' properties
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.

Adithya Baglody b0db28b512 drivers: Cmake: Add __ZEPHYR_SUPERVISOR__ macro for driver files.
Normally a syscall would check the current privilege level and then
decide to go to _impl_<syscall> directly or go through a
_handler_<syscall>.
__ZEPHYR_SUPERVISOR__ is a compiler optimization flag which will
make all the system calls from the driver files directly link
to the _impl_<syscall>. Thereby reducing the overhead of checking the
privileges.

In the previous implementation all the source files would be compiled
by zephyr_source() rule. This means that zephyr_* is a catchall CMake
library for source files that can be built purely with the include
paths, defines, and other compiler flags that all zephyr source
files uses. This states that adding one extra compiler flag for only
one complete directory would fail.
This limitation can be overcome by using zephyr_libray* APIs. This
creates a library for the required directories and it also supports
directory level properties.
Hence we use zephyr_library* to create a new library with
macro _ZEPHYR_SUPERVISOR_ for the optimization.

Armando Visconti b83d0782c9 sensor: vl53l0x: make xshut pin control optional
The XSHUT pin, used to shutdown the device when it is not
in current use, is optional and some boards (like ArgonKey)
leave it tied to vdd. So, the driver must provide a way to
make this part configurable.

Paul Sokolovsky 91228142fe sensors: Redefine SENSOR_CHAN_DISTANCE to be in meters
Most of sensor channels defined by Zephyr use the main, unscaled
SI unit. We also have SENSOR_CHAN_ALTITUDE which is defined in
meters. So, it only makes sense to define distance in meters too

The only driver supporting SENSOR_CHAN_DISTANCE as of now is
vl53l0x.c, which was updated accordingly. Also, update doc links
in the driver based on the review comment.

Kumar Gala b51cfeae60 sensors: dts: cleanup usage of HAS_DTS_I2C_DEVICE
Move to new Kconfig pattern in which we use an if !HAS_DTS_I2C_DEVICE
block for the Kconfig symbols that can now come from DT generation.
This pattern is useful to allow us to define default values for the
generated symbols for build-all testing.
