Subject: [PATCH v8] Add matrix keypad driver support for Mediatek SoCs 


Change since v7:
- specify compatible property as const string
- add maxItem in required property
- squash keypad example nodes
- sort header file with alphabetic order
- align all define values and add MTK_ prefix to make more uniform
- change debounce value to default 16ms if not specified in dts
- remove extra braces
- separate clk prepare as an internal driver function
- add special compatible string
- modify CONFIG_KEYBOARD_MTK_KPD=m to build keypad as ko module
