powerpc/cpm2: Fix set interrupt type
This is a simple change to correct problems when using set_irq_type
on platforms using CPM2. This code corrects the problem on most platform
but may have issues on 8272 derived platforms for some interrupts.
On 8272 PC2 & 3 are missing and PC 23 & 29 are added, which this patch
does not address.
