Subject: [PATCH 1/4] ath9k: move duplicated debug message to
'ath9k_hw_nvram_read'
The fill_eeprom functions are printing the same
debug message in case the 'ath9k_hw_nvram_read'
function fails. Remove the duplicated code from
fill_eeprom functions and add the ath_dbg call
directly into 'ath9k_hw_nvram_read'.

Subject: [PATCH 3/4] ath9k: use 'struct ath_hw *' as the first argument for
'ath9k_hw_nvram_read'
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.

Subject: [PATCH 4/4] ath9k: allow to load EEPROM content via firmware API
The calibration data for devices w/o a separate
EEPROM chip can be specified via the 'eeprom_data'
field of 'ath9k_platform_data'. The 'eeprom_data'
is usually filled from board specific setup
functions. It is easy if the EEPROM data is mapped
to the memory, but it can be complicated if it is
stored elsewhere.
The patch adds support for loading of the EEPROM
data via the firmware API to avoid this limitation.
