Subject: [PATCH v2] gpio/ls1043a: Add compatible "fsl,qoriq-gpio" for ls1043a gpio nodes

The compatible "fsl,qoriq-gpio" is used by gpio driver:
drivers/gpio/gpio-mpc8xxx.c to implement general gpio functionalities.

The chip-specific compatible "fsl,ls1043a-gpio" may be used to fix potential gpio IP block errata or other chip-specific gpio issues.

Signed-off-by: Liu Gang <Gang.Liu@xxxxxxx>

v2 changes:
	Add chip-specific compatible based on Scott's
	comment.
