This patch series adds support for the Khadas MCU and fan control for Khadas Edge 2 board.

The first patch updates the device tree bindings to add new "khadas,mcu-edge2" compatible for Khadas Edge 2.
The second mfd patch removes unused nvmem code.
The third patch adds the Khadas Edge 2 registers to the mfd driver.
The fourth patch adds support for Khadas Edge 2's new fan control registers to MCU thermal driver and the last one adds the Khadas Edge 2 device tree node for the MCU and fan control.
And the final patch adds the Khadas Edge 2 device tree node for the MCU and fan control.

Changes in v3:
- Renamed the compatible "khadas,mcu-v2" to "khadas,mcu-edge2" for Khadas Edge 2.
- Renamed KHADAS_MCU_V2 registers prefix to KHADAS_MCU_EDGE2.
- Used of_device_get_match_data instead of of_device_is_compatible to identify the MCU variant.

Changes in v2:
- Added a new compatible "khadas,mcu-v2" for Khadas Edge 2 instead of cooling-levels property in old variant.
- Added Khadas Edge 2 registers with KHADAS_MCU_EDGE2 prefix.
