Gabor Juhos 8384c0dba0 ath9k: add workaround for AR9331 USB host controller hang with USB1.1 devices 
When wifi radio is reset, some bits in (undocumented) USB registers may
flip. Patch adds setting them after radio reset (channel change, up/down).
With this patch stability of USB1.1 full-speed devices, connected directly
to AR9331 host port (no USB2.0 hub) is improved.

See "ar9331's usb stability issue" OpenWrt forum thread for details:
  <https://forum.openwrt.org/viewtopic.php?id=39956>

Based on QCA's Open HAL WAR_USB_DISABLE_PLL_LOCK_DETECT() macro:
  <https://github.com/qca/qcamain_open_hal_public/blob/master/hal/ar9300/ar9300_reset.c#L74>

Adapted to Linux mac80211 driver for 8Devices Carambola2 board by Mantas Pucka:

Ported to latest OpenWrt BB branch and tested on TP-Link TL-WR703N by
