The AR9003 family requires a change on the loop and can also skip
testing the PHY timing registers. This chip test can now be used
by all Atheros hardware families, including legacy. We can
eventually move this out to the generic ath module.

so it should not yet be enabled yet. When ANI will be

so fill the ANI functionality to all for AR9003 for now

The PHY split is easier done in a few steps. First move
the RF ops to the private ops and rename them accordingly.
We split PHY stuff up first for the AR5008 and AR9002
families. There are some callbacks that AR9002 share
with the AR5008 familiy so we set those first, if AR9002
has some different callbacks it will override them upon
hardware init.

This is used only once by ath9k_hw_process_ini() to
write an array of phy registers through REG_WRITE_ARRAY(),
but we already call REG_WRITE_ARRAY() multiple times
on the same caller so just remove this pointless wrapper.
We'll eventually just move the ath9k_hw_process_ini()
caller as an callback to abstract away between different
hardware families.
Although this change is subtle I should note that this
does change the delay pattern on writing the next series
of registers. REG_WRITE_ARRAY() uses a counter for each
register write and does a udelay(1) every 64 writes. By
removing this call it means that the counter is processed
for all the iniBB_RfGain registers and is incremented
on ath9k_hw_process_ini(), before this the after the call
ath9k_hw_write_regs() was made the register counter was
kept at the same index number prior to the call.

which differ considerably instead of adding branch checks for
