Move to CMake 3.20.0.
At the Toolchain WG it was decided to move to CMake 3.20.0.
The main reason for increasing CMake version is better toolchain
support.
Better toolchain support is added in the following CMake versions:
- armclang, CMake 3.15
- Intel oneAPI, CMake 3.20
- IAR, CMake 3.15 and 3.20

Now that device_api attribute is unmodified at runtime, as well as all
the other attributes, it is possible to switch all device driver
instance to be constant.
A coccinelle rule is used for this:

disable optional_qualifier

This sample controls up to 12 LEDs connected to a LP503x driver.
First, for each LED information is retrieved using the led_get_info
syscall and printed in the log messages. Next, from an infinite loop, a
test pattern (described below) is applied to all the LEDs simultaneously
(using the led_write_channels syscall) and then to each LED one by one
(using the led_set_{brightness,color} syscalls).
Test pattern:
For each color in red green blue white yellow purple cyan orange:
- set the color
- turn on
- turn off
- set the brightness gradually to the maximum level
- turn off
