[POWERPC] mpc512x: Add MPC512x PSC support to MPC52xx psc driver
Add 512x support using the psc_ops framework established with the previous patch. All 512x PSCs share the same interrupt so add IRQF_SHARED to irq flags. Signed-off-by: John Rigby <jrigby@freescale.com> Signed-off-by: Grant Likely <grant.likely@secretlab.ca>
