Sujith e9141f71f4 ath9k_hw: Fix async fifo for AR9287
Async fifo is now enabled only for versions 1.3 and above.
Enable it in the appropriate place, in the reset routine,
instead of process_ini().

Luis R. Rodriguez 795f5e2ca6 ath9k_hw: split calib code by hardware families
Calibration code touches phy registers and since these
change the calibration code needs to be abstracted.

Noise floor calibration is the only thing remaining but
since the remaining calls only touch the AR_PHY_AGC_CONTROL
register we'll just define that register conditionally, that
will be done separately. The goal is to remove the dependency
of ar9002_phy.h on calib.c

This also adds stubs to be filled for AR9003 calibration code.

Pavel Roskin 152d530d9e ath9k: remove ah->mask_reg, it's never used properly
ah->mask_reg was used to hold different data throughout the driver.
ath9k_hw_init_interrupt_masks() used it to save the value written to
AR_IMR.  ath9k_hw_set_interrupts() used it to hold the interrupt mask as
defined in enum ath9k_int.  Those masks differ in many bits.

Use ah->imask instead of ah->mask_reg in ath9k_hw_set_interrupts() and
ath9k_hw_updatetxtriglevel().  That's what the code was meant to do.
ah->imask is initialized in ath9k_start(), so we don't need to
initialize it from ah->mask_reg.

Once it's done, ah->mask_reg becomes write-only, so it's replaced with a
local variable in ath9k_hw_init_interrupt_masks().
