[PATCH 1/2] MIPS: ath79: fix AR933X WMAC reset code

References: <1331720916-4015-1-git-send-email-juhosg@openwrt.org>
Sender: linux-mips-bounce@linux-mips.org
The current code puts the built-in WMAC device of the
AR933X SoCs into reset instead of starting it. This
causes a hard lock on AR933X based boards when the
wireless driver tries to access the device.
