Subject[PATCH 15/16] staging: wilc1000: fix const cast warnings
Date
The wilc1000 driver produces a lot of warnings about invalid
casts between const and non-const variables. This reworks
the code to avoid all those warnings, by marking variables
and function arguments const.

A lot of the types use WILC_Uint8, I change them to const u8
for style reasons, as I'm touching them anyway.
