Change since V2:
- add wakeup source optional property in dts node
- update debounce time as microsecond
- remove origin hw-map-num and hw-init-map properties
- use matrix-map to define keypad rows, columns and keymap
- remove tasklet and use thread irq to deal with keypad interrupt
- use devm_XXX API to get device resources
- modify dts parser using matrix-map API
- modify irq handlers using for_each_set_bit to detect which key status changed
- remove surplus log
- remove surpluse header file
- replace readw with memcpy_fromio to get keypad status registers value
- fixed other issue according reviewer comments
