MFC r276047: Add -march=armv7a to the kernel compile for all v7a ARM systems.

MFC r261252, r261279, r261304, r261305, r261322, r261336, r261337, r261338,

Fix the name of the dts file for the HL201...

When mapping an address, the bsh needs the same offset we do for other things.

Add explicit depends on bus_if.h and device_if.h to avoid a

devices. This is a nop, except for what's reported by atmelbus for the
resources.

Comment cleanups. Move things around for diff reduction against FDT work.
