Remove all stuff related to __ARM_ARCH >= 6 from pmap.h header except
for <machine/pmap-v6.h> include. It was used by old pmap-v6 code.

Retire pmap_pte_init_mmu_v6() which was used by old pmap-v6.

Use kernel_pmap directly instead of pmap_kernel(). The kernel_pmap is
already used for __ARM_ARCH >= 6 and so even for __ARM_ARCH < 6 on some
common places.

ARM: remove old pmap-v6 code. The new pmap-v6 is mature enough, and
dual implementation is showstopper for major cleanup.

This patch only removes old code from tree. Cleanups will follow asap.

Add a pmap_kremove_device() to undo mappings made with pmap_kenter_device().

Previously we used pmap_kremove(), but with ARM_NEW_PMAP it does the remove
in a way that isn't SMP-coherent (which is appropriate in some circumstances
such as mapping/unmapping sf buffers). With matching enter/remove routines
for device mappings, each low-level implementation can do the right thing.
