We add this now as OFDM spur mitigation required accessing
the EEPROM for the AR9003 devices.

Once upon a time the AR_EEPROM_MAC macro was added to let us
add a random attribute to the three 4-bytes of MAC addresses
entries we read from the EEPROM. This was good while a random
high-enough value was used which did not conflict with any
of the already existing enum eeprom_param values. With AR9003
support the enums overlap and it means we either increment
the random offset or just restore the reading logic to match
what the HAL has. I choose to do the later to synchronize
the logic on both code bases.
This should fix reading the MAC address from the EEPROM
on AR9003 hardware.

The AR9003 TX/RX gain is currently initialized with the other
components, so for now AR9003 does not implment this callback,
after hardware bring up we can test moving the TX/RX gain there
as well and if it works well move them to its own callback as
well.
Since all INI stuff is now moved out hw.c no longer needs to
include and touch any original INI headers/structs.

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.
