ath5k_hw_reset() was always setting initval and eeprom settings for B mode
when using G mode. This is because a B channel was being picked up first. We
should first instead check for G channel. This patch also introduces a
driver_mode variable which should be used instead for determing
more reliably the mode we're in.
This fixing another bug where IQ calibration was not being run for
G mode as CHANNEL_B was always being picked up first. We now instead
check for driver_mode.
Similar problem was occurring in ath5k_hw_rf5112_rfregs(), we fix this
there too.
