d0f63b2021 wl1271: fix endianess issues
We were not handling endianess correctly.  The wl1271 chip runs on
little-endian values.  This patch makes sure that all the communication with
the wl1271 firmware is done in little-endian by using cpu_to_le* and
le*_to_cpu where appropriate.

Also, all the struct definitions for data exchanged with the firmware has
been changed to use __le16/32 types instead of u16/32.

This fixes a few sparse warnings, such as these:

37079a831d wl1271: enable HW_AVAILABLE interrupt to fix ELP
We need to listen to HW_AVAILABLE interrupts when using ELP with firmware
revision 6.1.0.0.241.  Add WL1271_ACX_INTR_HW_AVAILABLE to the interrupts that
are enabled by default.

ac78403e14 wl1271: add workaround to avoid distortion due to excessive tx power
We still don't have proper calibration for our devices, so we are using way
too much power for TX, which causes a lot of distortion.  This hack hardcodes
the txpower to 7dBm.

d6e19d135d wl1271: workaround to send a disconnect before rejoining
We don't get any indication from the stack when we have disassociated.  In
wl1271, it is important to send a CMD_DISCONNECT before joining again,
because the firmware cleans some things up.  So we check if we're already
joined and disconnect if that's the case.

be823e5b2d wl1271: Mask unneeded events from firmware to conserve power
Currently several events are enabled from the firmware for which there
is no handling. This wakes up the host unnecessarily. Mask those
unneeded events.

1fba49741d wl1271: Use vmalloc to allocate memory for firmware
Use vmalloc to allocate memory for the firmware image, and use a smaller
linear buffer for the actual transfer of the firmware to the chipset.

This patch is an adaptation of a similar patch for wl1251 by Kalle Valo.
