m68knommu: fix definitions of __pa() and __va()
Fix compilation breakage of all m68knommu targets:
CC arch/m68knommu/kernel/asm-offsets.s
In file included from include/linux/sched.h:77,
from arch/m68knommu/kernel/asm-offsets.c:12:
include/linux/percpu.h: In function 'per_cpu_ptr_to_phys':
include/linux/percpu.h:161: error: implicit declaration of function 'virt_to_phy
This is broken in linux-2.6.33-rc3.
Change the definitions of __pa() and __va() to not use virt_to_phys()
and phys_to_virt(). Trivial 1:1 conversion required for the non-MMU case.
A side effect if this is that the m68knommu can now use asm/virtconvert.h
for the definition of virt_to_phys() and phys_to_virt().
Also cleaned up the definition of page_to_phys() when moving into
virtconvert.h.
