irqchip/irq-pic32-evic: update include to use pic32.h from platform_data

Use the linux/platform_data/pic32.h include instead of
asm/mach-pic32/pic32.h so that the asm variant can be dropped. This
is in preparation for allowing some drivers to be compiled on other
architectures with COMPILE_TEST enabled.
