Programming the opmode in the HW can be done
before the assoc_id and STA_ID registers are
setup. This helps ath9k_htc when multiple register
writes are used.

This patch adds support for writing multiple registers
in a single USB command.
Specific calls from the HW code that performs multiple
register writes would be modified to make use of this
in subsequent patches.

According to tests, both TSF lower and upper registers kept counting, so
the higher part could have been updated after the lower part has been
read, as shown in the following log where the upper part is read first
and the lower part next.
tsf = {00000003-fffffffd}
tsf = {00000003-00000001}
tsf = {00000004-0000000b}
This patch corrects this by checking that the upper part has not been
changed while the lower part was read. It has been tested in an IBSS
network where artifical IBSS merges have been done in order to trigger
hundreds of rollover for the TSF lower part.
It follows the logic mentionned by Derek, with only 2 register reads
needed at each additional steps instead of 3 (the minimum number of
register reads is still 3).

The AR9002 hardware code enables aggregation for WEP but
mac80211 doesn't enable aggregation with WEP, and the AR9003
code family does not need this so skip it for now for AR9003
but leave the code and annotate we should eventually consider
how to remove this in consideration for the HAL unification
goals.

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.
