From: Leo Kim <leo.kim@xxxxxxxxx>
There are over-commenting in the wilc_wfi_cfgoperations.c file and most of them
are not helpful to explain what the code does and generate 80 ending
line over warnings. So, all of comments are removed in this patch and the
comments will later be added if necessary with the preferred Linux style.
