When antenna diversity combining is enabled in the EEPROM,
the initial values for the MAIN/ALT config have to be
programmed correctly. This patch adds it for AR9285.

Since the diversity combining macros are common to all chip
families, remove the redundant AR9285 macros and move the
definitions to phy.h.

CUS198 is a card based on AR9485. There are differences
between the base reference design HB125 and CUS198.
Identify such cards based on the PCI subsystem IDs and
set HW parameters appropriately.

The 'ath9k_hw_nvram_read' function takes a
'struct ath_common *' as its first argument.
Almost each of its caller has a 'struct ath_hw *'
parameter in their argument list, and that is
dereferenced in order to get the 'struct ath_common'
pointer.

Change the first argument of 'ath9k_hw_nvram_read'
to be a 'struct ath_hw *', and remove the dereference
calls from the callers.

Also change the type of the first argument of the
ar9300_eeprom_read_{byte,word} functions.

The simulataneous transmission of both WLAN and BT might cause
increase in power levels. To avoid regulatory violation, WLAN tx
power will be adjusted according to BT power index based on avaliability
of BT scheduling messages. WLAN tx power reduction might affect its
performance. So WLAN tx power is only be lowered when the signal strength
is good enough. Otherwise concurrent tx will be disabled and WLAN uses
it default power levels. Also concurrent tx is disabled whenever WLAN is
moving to off-channel which might be used by BT.

two can be out of sync.

unnecessary casts.  I manually removed the conversions this
script produces of casts with __force, __iomem and __user.

The current code unconditionally reads the target
power values for all modes from the EEPROM. However
In 'ar9003_hw_set_power_per_rate_table' the regulatory
caps are applied only on a mode specific subset of the
power values.

The reported TX power level is calculated from the
maximum of the power values. Because some of these
values are uncapped in certain cases, the reported
TX power will be wrong.

On the older chipset, we don't have such problems
because only the mode specific subset of the power
levels are retrieved from the EEPROM on those. Do
the same for the AR9003 chips to fix the issue.
