This patch was tested on AM335x-EVM and based on linux-next, cleanly
applies on top of "input/next"

Changes from v5:
	- Updated based on Dmitry's patch.
	  * Modified the driver acc. to matrix_keypad_build_keymap()
	    recent update.
	  * Combined row_gpios & col_gpios devm_kzalloc's to single
	    devm_kzalloc.
	  * Added proper return values for different failures in
	    matrix_keypad_parse_dt().

Changes from v4:
	- Removed clustered-irq support through DT. This should be
	  added if any platform requires in the future.

Changes from v3:
	- Incorporated Stephen Warren's review comments on v3
	  * Added description to clustered-irq-flags binding

Changes from v2:
	- Incorporated Stephen Warren's review comments on v2
