We should not be idle when we get the ATH9K_INT_TIM_TIMER,
otherwise we wake up the chip and that throws off the idle
state, the driver needs to be in full sleep when idle and
nothing should turn it awake without turning it back to
full sleep again. If we leave the chip idle and suspend,
upon resume the device will become unusable and we get:
ath: Starting driver with initial channel: 5745 MHz
ath: timeout (100000 us) on reg 0x7000: 0xdeadbeef & 0x00000003 != 0x00000000
