[PATCH v2] staging: rtl8723bs: remove unused struct rtw_regulatory

[deep]

From: Kenet Jovan Sokoli <deep@xxxxxxxxxxxxxxxxxx>

The struct rtw_regulatory is never used in the rtl8723bs driver.
Functions taking it as a parameter are always passed NULL and
perform no logic with it. Remove the dead code and the struct.

Suggested by: Dan Carpenter dan.carpenter@xxxxxxxxxx
Signed-off-by: Kenet Jovan Sokoli <deep@xxxxxxxxxxxxxxxxxx>

v2: Completely refactored the logic to remove the functions and the
struct entirely as suggested by Dan Carpenter. I'm still learning
the ropes with Git, so I messed up on how to
perform a proper cleanup!
