gpu: ipu-v3: Select GENERIC_IRQ_CHIP to fix build error

This driver uses GENERIC_IRQ_CHIP, so it needs to select GENERIC_IRQ_CHIP to
avoid build error.

Fixes below build errors:
ERROR: "irq_alloc_domain_generic_chips" [drivers/gpu/ipu-v3/imx-ipu-v3.ko] undefined!
ERROR: "irq_gc_mask_clr_bit" [drivers/gpu/ipu-v3/imx-ipu-v3.ko] undefined!
ERROR: "irq_gc_mask_set_bit" [drivers/gpu/ipu-v3/imx-ipu-v3.ko] undefined!
