irqchip/irq-pic32-evic: Only include asm headers when compiling for MIPS

The asm headers are not actually needed when compiling on architectures
other than MIPS, and traps.h is not available on all architectures.

Include them on MIPS systems so that this driver can be compiled on other
architectures.
