Closed drivers kill radio right after reading radio version and MACCTL,
so it was easy to find related PHY ops:
phy_read(0x0810) -> 0x0000
phy_write(0x0810) <- 0x0000
To find out the mask of above OP, MMIO hack was used to fake read val:
phy_read(0x0810) -> 0xffff
phy_write(0x0810) <- 0x0000

checking the status of PAPRD_AGC2_POWER(Log(ADC_power) measured after

done. This is an additional check apart from polling for PAPRD done bit being set.
Susinder suggests that the ideal power range value should be
0xf0 to 0xfe. With AR9382 we do have the values in this range. to have a
common check for all platforms we take agc2_power should be atleast greater
than 0xe0
