This adds minimal support for the MediaTek 8365 SOC and the EVK reference
board, allowing the board to boot to initramfs with serial port I/O.
v4:
- Remove pins-are-numbered references that have been holding things up
now that the patches removing it from dt-bindings have landed in linux-next
v3:
- Remove a number of components that are not yet supported (they will
come back alongside the corresponding drivers)
- Address issues found by dt_binding_check (mostly fixing pinctrl
bindings)
- Address issues pointed out in comments
- Reorder patches
v2:
- Add missing dt-bindings documentation
- Small cleanups addressing issues in v1 pointed out by Krzysztof Kozlowski

+ Describe the specific driving setup property.
+ For I2C pins, the existing generic driving setup can only support
+ 2/4/6/8/10/12/14/16mA driving. But in specific driving setup, they
+ can support 0.125/0.25/0.5/1mA adjustment. If we enable specific
+ driving setup, the existing generic setup will be disabled.
+ The specific driving setup is controlled by E1E0EN.
+ When E1=0/E0=0, the strength is 0.125mA.
+ When E1=0/E0=1, the strength is 0.25mA.
+ When E1=1/E0=0, the strength is 0.5mA.
+ When E1=1/E0=1, the strength is 1mA.
+ EN is used to enable or disable the specific driving setup.
+ Valid arguments are described as below:
+ 0: (E1, E0, EN) = (0, 0, 0)
+ 1: (E1, E0, EN) = (0, 0, 1)
+ 2: (E1, E0, EN) = (0, 1, 0)

+ 6: (E1, E0, EN) = (1, 1, 0)
+ 7: (E1, E0, EN) = (1, 1, 1)
