Before transmission when aligning the buffer to 4-byte bounday, tx_hdr
needs to be updated. Otherwise debug logs print false data.

Now that necessary commands for WMM are implemented, implement queue handling
for WMM. But WMM is not enabled yet, only one queue is used.

This change moves all of the spi specific code from main.c into
spi.c.  The module initialization code also moves, but common
code for initializing mac80211 etc. stays in main.c, as this will
eventually form a common library module also used by wl1251_sdio.

In order to eventually support wl1251 spi and sdio interfaces, move
the register and memory transfer functions to a common file.  Also
rename wl1251_spi_mem_{read,write} to indicate its common usage.
We still use spi_read internally until SDIO interface is introduced
so nothing functional should change here.

Check the return call from wl12xx_ps_elp_wakeup() and bail out if it
fails. This shouldn't happen, but if does there's a fundamental low
level issue.

wl12xx is a driver for TI wl1251 802.11 chipset designed for embedded
devices, supporting both SDIO and SPI busses. Currently the driver
supports only SPI. Adding support 1253 (the 5 GHz version) should be
relatively easy. More information here:
