ath5k: write PCU registers on initial reset
Bob Copeland [Sun, 5 Jul 2009 01:03:13 +0000 (21:03 -0400)]
"Ath5k: unify resets"
introduced a regression into 2.6.28 where the PCU registers are never
initialized, due to ath5k_reset() always passing true for change_channel.
We subsequently program a lot of these registers but several may start
in an unknown state.
