ath79: ag71xx: Unify debug output with ar71xx and make debugging easier

Currently it's quite hard to diff debugging output between ar71xx and
ath79, so this patch tries to improve it by adding the same
ag71xx_dump_regs function and placing debugging output from the
registers to relatively same places.
