On AR9285, the antenna switch configuration register uses more than just
16 bits. Because of an arbitrary mask applied to the EEPROM value that
stores this configuration, diversity was broken in some cases, leading
to a significant degradation in signal strength.
Fix this by changing the callback to return a 32 bit value and remove
the arbitrary mask.

Remove the double swapping of the descriptor data structure, instead
keep it little-endian (native format of the eeprom data), and byteswap
on access.
This allows sparse to verify endian access to the eeprom struct.

Since the new AR9003 EEPROM code does tune the card for the configured
tx power level, we need to fill in the correct power limits in the TPC
part of the DMA descriptor.

This is done depending on what the EEPROM settings indicates.
