This is a draft of supporting 64-bit clock module index on NuMaker SoC series.
Relevant points include:
1. No m55m1x yet, take m2l31x as an example
2. Create new binding file nuvoton,numaker-pcc-modidx64.yaml for SoC with 64-bit clock module index
3. In clock header file for DT, 64-bit value of FOO_MODULE macro expands to two 32-bit cells in BE order
NOTE: See dt-bindings/clock/numaker_m2l31x_clock.h
NOTE: Check the link for requirement of 64-bit integer in zephyr
https://docs.zephyrproject.org/latest/build/dts/intro-syntax-structure.html
4. Clock ontrol driver is soc-conditional on clock module index
5. Other drivers (gpio, serial, etc.) also must be soc-conditional on clock module index

Current code does not build on Cortex-M0, seems like it does not like subs: Error: instruction not supported in Thumb16 mode -- `subs r3,#1' Adding a unified assembler language declaration in the snippet seems to fix the problem, also add an M0+ board so this is tested in CI.

Add possibility to perform crop on all pipes and compose (downscale) on pixel pipes (endpoint #1 and endpoint #2). Rework the code in order to move the downscale control from the set_fmt into the set_selection (compose). Signed-off-by: Alain Volmat <[email protected]>

Add support for NV12/NV21, NV16/NV61 and YUV420/YVU420 (semi)planar formats which can be output by the main #1 pipe. Signed-off-by: Alain Volmat <[email protected]>
