[PATCH] staging: rtl8723bs: remove static HalDetectPwrDownMode() function

[Nikolay Kulikov <nikolayof23@gmail.com>]

The return value of this function is ignored at the call site, and since
the function has no side effects (except for the assignment to
pHalData->pwrdown, which is not used anywhere else), it can be removed.

At the same time, remove the efuse shadow functions, as they are
becoming unused.
