[PATCH] gpio/ls2080a: Add compatible "fsl, ls2080a-gpio" for ls2080a gpio nodes

[Liu Gang]

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,ls2080a-gpio" may be
used to fix potential gpio IP block errata or other
chip-specific gpio issues.
