Subject: [PATCH v6] Add mtk matrix keypad driver for keypad on MTK SoC

Change since v5:
- remove unnecessary include files

- use local irqnr variable instead of member variable of mtk_keypad struct
- use regmap to read and write registers
- drop kpd_get_dts_info directly into probe function
- use devm_add_action_or_reset to avoid goto error handling when do clk setting
- use devm_request_threaded_irq api to request irq
- remove platform_set_drvdata
