arm64: dts: 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.
