powerpc: Fix DEBUG_HIGHMEM build break from d4515646699
Code was added to mm/higmem.c that depends on several
kmap types that powerpc does not support. We add dummy
invalid definitions for KM_NMI, KM_NM_PTE, and KM_IRQ_PTE.
According to list discussion, this fix should not be needed
anymore starting with 2.6.33. The code is commented to this
effect so hopefully we will remember to remove this.
