* irq/irq.h, irq/irq.c (removed), irq/no_pic.c (added),
	irq/irq_init.c, Makefile.am: The PSIM BSP (currently)
	has no support for an interrupt controller or interrupts
	other than the decrementer. Removed all definitions for PCI + ISA
	interrupts and all unnecessary code (leftovers from copying).
	Separated PIC-specific bits into 'no_pic.c' which allows us
	to use 'irq.c' (i.e., more code) from 'shared'.
