MIPS: BCM47xx: fix build with GENERIC_GPIO configuration

Since eb9ae7f2 (gpio: fix build error in include/asm-generic/gpio.h)
the generic version of gpio.h calls __gpio_{set,get}_value which we
do not define. Get rid of asm-generic/gpio.h and define the missing
stubs directly for BCM47xx to build.
