[ Upstream commit 969ac78db78c723a24e9410666b457cc1b0cb3c3 ]

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'
mips-linux-ld: irq-goldfish-pic.c:(.init.text+0xf4): undefined reference to `irq_gc_unmask_enable_reg'
mips-linux-ld: irq-goldfish-pic.c:(.init.text+0xf8): undefined reference to `irq_gc_unmask_enable_reg'
mips-linux-ld: irq-goldfish-pic.c:(.init.text+0x100): undefined reference to `irq_gc_mask_disable_reg'
mips-linux-ld: irq-goldfish-pic.c:(.init.text+0x104): undefined reference to `irq_gc_mask_disable_reg'
mips-linux-ld: irq-goldfish-pic.c:(.init.text+0x11c): undefined reference to `irq_setup_generic_chip'
mips-linux-ld: irq-goldfish-pic.c:(.init.text+0x168): undefined reference to `irq_remove_generic_chip'

Fixes: 4235ff50cf98 ("irqchip/irq-goldfish-pic: Add Goldfish PIC driver")
