Miaoqing Pan 466b0f0208 ath9k: fix data bus error on ar9300 and ar9580
One crash issue be found on ar9300: RTC_RC reg read leads crash, leading
the data bus error, due to RTC_RC reg write not happen properly.

Warm Reset trigger in continuous beacon stuck for one of the customer for
other chip, noticed the MAC was stuck in RTC reset. After analysis noticed
DMA did not complete when RTC was put in reset.

So, before resetting the MAC need to make sure there are no pending DMA
transactions because this reset does not reset all parts of the chip.

The 12th and 11th bit of MAC _DMA_CFG register used to do that.
	12 cfg_halt_ack 0x0
		0 DMA has not yet halted
		1 DMA has halted
	11 cfg_halt_req 0x0
		0 DMA logic operates normally
		1 Request DMA logic to stop so software can reset the MAC

The Bit [12] of this register indicates when the halt has taken effect or
not. the DMA halt IS NOT recoverable; once software sets bit [11] to
request a DMA halt, software must wait for bit [12] to be set and reset
the MAC.

So, the same thing we implemented for ar9580 chip.
