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:
