70e3e8a6e8 iwlagn: remove indirection for eeprom_query_addr
Not needed since the driver split.  Eliminate redundant routine.

16b80b714f iwlagn: semaphore and calib cleanup
All agn devices use the same eeprom semaphore and calib version routines.
Delete the indirection and move the semaphore routines to where they are
used and make static.

02a7fa00a6 iwlagn: move IO functions out of line
This generates a massive reduction in module size:
with debug:
   text	   data	    bss	    dec	    hex	filename
 670300	  13136	    420	 683856	  a6f50	iwlagn.ko (before)
 388347	  13136	    408	 401891	  621e3	iwlagn.ko (after)

without debug:
   text	   data	    bss	    dec	    hex	filename
 528575	  13072	    420	 542067	  84573	iwlagn.ko (before)
 294192	  13072	    408	 307672	  4b1d8	iwlagn.ko (after)

This also removes all the IO debug functionality since
it can easily be replaced by tracing, and makes the
code unnecessarily complex.

I haven't done any CPU utilisation measurements, but
given that the hotpaths don't use much IO it is not
likely to have a negative impact; in fact, the size
reduction will reduce cache pressure which possibly
improves performance.

Finally, an unused function or two were removed.

239712ebb2 iwlwifi: don't read sku information from EEPROM for 4965
For all the new devices, the sku information should read from EEPROM
but for legacy devices such as 4965, appearly the EEPROM does not
contain the necessary information. so skip the read from EEPROM
and go back to use software configuration.

38d59392b2 iwlwifi: fix valid chain reading from EEPROM
When read valid tx/rx chains from EEPROM, there is a bug to use the
tx chain value for both tx and rx, the result of this cause low
receive throughput on 1x2 devices becuase rx will only utilize single
chain instead of two chains

c6fc108776 iwlagn: remove old EEPROM TX power reading
This removes the old TX power reading code, it isn't
necessary since the new code is able to read all the
various EEPROM layouts due to relying on information
contained in the EEPROM.

8d6748ca73 iwlagn: implement layout-agnostic EEPROM reading
The current EEPROM reading code has some layout
assumptions that now turned out to be false with
some newer versions of the EEPROM. Luckily, we
can avoid all such assumptions by using data in
the EEPROM itself, so implement using that.

However, for risk mitigation purposes, keep the
old reading code for current hardware for now.

the next patch, so rename them to their correct

reading them accordingly.

dbbf1755b0 iwlwifi: use antenna information in EEPROM
The valid tx/rx antenna information is part of EEPROM, so use it
to configure the device.

For few cases, the EEPROM did not reflect the correct antenna, but
it is too late to modify the EEPROM, so overwrite with .cfg parameters
