gpio: rockchip: needs GENERIC_IRQ_CHIP to fix build errors

gpio-rockchip uses interfaces that are provided by the Kconfig
symbol GENERIC_IRQ_CHIP, so the driver should select that symbol
in order to prevent build errors.

Fixes these build errors (and more):

aarch64-linux-ld: drivers/gpio/gpio-rockchip.o: in function `rockchip_irq_disable':
gpio-rockchip.c:(.text+0x454): undefined reference to `irq_gc_mask_set_bit'
