MIPS: BCM47xx: Select GPIOLIB for BCMA on bcm47xx platform

The Kconfig items BCM47XX_BCMA and BCM47XX_SSB selected respectively
BCMA_DRIVER_GPIO and SSB_DRIVER_GPIO. These options depend on GPIOLIB
without explicitly selecting it so it results in a warning when GPIOLIB
is not set:

scripts/kconfig/conf --oldconfig Kconfig
warning: (BCM47XX_BCMA) selects BCMA_DRIVER_GPIO ... unmet direct
	dependencies (BCMA_POSSIBLE && BCMA && GPIOLIB)
warning: (BCM47XX_SSB) selects SSB_DRIVER_GPIO ... unmet direct
	dependencies (SSB_POSSIBLE && SSB && GPIOLIB)

which subsequently results in compile errors.
