staging: rtl8723au: phy_SsPwrSwitch92CU() was never called with bRegSSPwrLvl != 1
Get rid of the alternate code paths since these weren't used and have never been tested according to the in-code comments. Signed-off-by: Jes Sorensen <Jes.Sorensen@redhat.com> Signed-off-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org>
