powerpc/mpc5200: Document and tidy irq driver
This patch adds documentation to the mpc5200 interrupt controller driver and cleans up some minor coding conventions. It also moves the contents of mpc52xx_pic.h into the driver proper (except for a small common bit that is moved to the common mpc52xx.h) because the information encoded there is not required by any other part of kernel code. Finally for code readability sake, the L2_OFFSET shift value is removed because the code using it resolves to a noop. Signed-off-by: Grant Likely <grant.likely@secretlab.ca>
