The new Khadas VIM2, VIM3 and Edge boards embeds an on-board microcontroller
connected via I2C.

This Microcontroller is present on the Khadas VIM1, VIM2, VIM3 and Edge
boards.

It has multiple boot control features like password check, power-on
options, power-off control and system FAN control on recent boards.

Thie serie adds :
- the Thermal Cooling cell driver
- add support into the Khadas VIM3/VIM3L DT

Changes since v4 at [5]:
- Removed ctx checks in thermal driver
- Removed the useless khadas_mcu_fan_disable() helper in thermal driver
- Fixed a small indentation issue in thermal driver

Changes since v3 at [4]:
- Removed Applied patches 1, 2 & 4
- Added reviewed-by tags for patch 3 & 5

Changes since v2 at [3]:
- Removed NVMEM driver for separate submission
- fixed MFD driver, header and Kconfig
- fixed Thermal Kconfig
- fixed MAINTAINERS files and path

Changes since RFC v1 at [2]:
- moved hwmon driver to thermal-only
- moved the SM1 thermal nodes in a separate serie
- added the bindings review tag from rob
