skrll | Fix the armv[67] memory attributes for uncached memory. Previously it was
mapped as strongly-ordered which meant that unaligned accesses would fault.
armv7_generic_bs_map now maps pages with PMAP_DEV which is treated as SO
bus_dma continues to use PMAP_NOCACHE as appropriate, but this now get
mapped to the correct memory attribute bits for armv[67]
DEVMAP_ENTRY usees a new flag PTE_DEV.
The workaround for the unaligned access faults is now removed.
XXX Other armv[67] boards bus_space implementations should be checked.
XXX There is scope to reduce the difference to aarch64

On second thought, get rid of "bs_base" from struct bus_space and use a
custom bs_map for acpipchb instead.

jmcneill | Add a "bs_base" field to struct bus_space. If present, use it to translate
mappings by appending the value to the pa passed to bus_space_map.

Add initial support for ARMv8 (AARCH64) (by nisimura@ and ryo@)
- sys/arch/evbarm64 is gone and integrated into sys/arch/evbarm. (by skrll@)
- add support fdt. evbarm/conf/GENERIC64 fdt (bcm2837,sunxi,tegra) based generic 64bit kernel config. (by skrll@, jmcneill@)

no functional change.
