Rafal Jaworowski b949475db0 Introduce superpages support for ARMv6/v7. 
Promoting base pages to superpages can increase TLB coverage and allow for
efficient use of page table entries.  This development provides FreeBSD/ARM
with superpages management mechanism roughly equivalent to what we have for
i386 and amd64 architectures.

1. Add mechanism for automatic promotion of 4KB page mappings to 1MB section
   mappings (and demotion when not needed, respectively).

2. Managed and non-kernel mappings are now superpages-aware.

3. The functionality can be enabled by setting "vm.pmap.sp_enabled" tunable to
   a non-zero value (either in loader.conf or by modifying "sp_enabled"
   variable in pmap-v6.c file).  By default, automatic promotion is currently
   disabled.
