[RFC v2][PATCH 30/35] m68k: use pte_offset_kernel() as base for pte_offset_map*()

Some architectures use pte_offset_map() as a basis for
pte_offset_kernel(). Others do the inverse.

Although arbitrary, Using pte_offset_kernel() as the base
seems a wee bit more popular and it also fits in well
with the way I'm breaking out the headers.

Instead of coding the same implementation twice, this
makes pte_offset_map{,_nested}() call pte_offset_kernel()
directly.
