amdfam10: Convert to board_reset()

And here comes the mess...

This just renames do_hard_reset() to do_board_reset() and keeps current
behaviour. As these are never called from chipset or board code but only
from common code, it's likely that their implementations are untested
and not what we actually want. Also note, that sometimes implementations
for rom- and ramstage differ considerably.
