irqchip/goldfish-pic: Select GENERIC_IRQ_CHIP to fix build

irq-goldfish-pic uses GENERIC_IRQ_CHIP interfaces so select that symbol
to fix build errors.

Fixes these build errors:

mips-linux-ld: drivers/irqchip/irq-goldfish-pic.o: in function `goldfish_pic_of_init':
irq-goldfish-pic.c:(.init.text+0xc0): undefined reference to `irq_alloc_generic_chip'
