The EEPROM PAPRD rate mask fields only contain mask values for actual
rates in the low 25 bits. The upper bits are reserved for tx power
scale values. Add the proper mask definitions and use them before
writing the values to the register.

This helper function would be used for AR9485.

Calibration data are stored at 4k address (0xfff). The cal data
for AR9485 is not compressed so its lengh can exceed 1024 limit,
take care of that.

Parsing data using bitfields is messy, because it makes endian handling
much harder. AR9002 and earlier got it right, AR9003 got it wrong.
This might lead to either using too high or too low tx power values,
depending on frequency and eeprom settings.
Fix it by getting rid of the CTL related bitfields entirely and use
masks instead.

Some of the new AR9003 cards do not come with an external EEPROM chip
anymore. Calibration data on these cards is stored in the OTP ROM on
the chip.
This patch adds support for reading this data, and also adds support
for different EEPROM chip sizes (512 bytes instead of 1K).

Add eeprom base extension structures which are needed for

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.

This is done depending on what the EEPROM settings indicates.
