This reverts commit 5a254ffe.

The commit failed to take into account that allocated wireless devices
(wiphys) are not added into the device list upon allocation, but only
when they are registered. Therefore, it opened up a race between
allocating and registering a name, so that if two processes allocate and
register concurrently ("alloc, alloc, register, register" rather than
"alloc, register, alloc, register") the code will attempt to use the
same name twice.

Enable runtime PM for the wl1271 SDIO device.

We request power whenever the WLAN interface is brought up,
and release it after the WLAN interface is taken down.

As a result, power is released immediately after probe returns,
since at that point power has not been explicitly requested yet
(i.e. the WLAN interface is still down).

6000g2 devices need to have temperature offset calibration. The runtime
uCode needs to receive the calibration results just like BB and LO
calibration. To do this, driver reads the offset value from NVM and send
it to uCode after runtime uCode is alive.

iwlagn driver uses the IWL_MAX_STANDARD_PHY_CALIBRATE_TBL_SIZE
as the chain noise reset calibration index and
IWL_MAX_STANDARD_PHY_CALIBRATE_TBL_SIZE+1 as the chain noise gain
calibration index, if not specified by the TLV value in the new
firmware format.

However, this is broken if we need to add more calibrations like
the temperature offset calibration because we increased
IWL_MAX_STANDARD_PHY_CALIBRATE_TBL_SIZE by 1.

To fix this issue, define IWL_DEFAULT_STANDARD_PHY_CALIBRATE_TBL_SIZE
and use it as the calibration index instead. We still keep the
IWL_MAX_STANDARD_PHY_CALIBRATE_TBL_SIZE as a sanity check for
the TLV value given by ucode.

By duplicating a little bit of code between 3945
and agn, we can move a lot of code into an agn
specific station management file and thus reduce
the amount of code in core that is dead to 3945.

before:
   text	   data	    bss	    dec	    hex	filename
 212886	   3872	     96	 216854	  34f16	iwlcore.ko
 620542	  10448	    304	 631294	  9a1fe	iwlagn.ko
 314013	   3264	    196	 317473	  4d821	iwl3945.ko

after:
   text	   data	    bss	    dec	    hex	filename
 202857	   3872	     92	 206821	  327e5	iwlcore.ko
 629102	  10448	    308	 639858	  9c372	iwlagn.ko
 314240	   3264	    196	 317700	  4d904	iwl3945.ko

delta:
 -10029   iwlcore.ko
   8560   iwlagn.ko
    227   iwl3945.ko

so it's a net win even if you have both loaded,
likely because a lot of EXPORT_SYMBOLs go away.
