commit 605d7c0b05 upstream.
Clear bit 8 of REG_SYS_STATUS1 after MAC power on.
Without this, some RTL8821CU and RTL8811CU cannot connect to any
network:

Feb 19 13:33:15 ideapad2 kernel: wlp3s0f3u2: authentication with
90:55:de:__:__:__ timed out
The RTL8822CU and RTL8822BU out-of-tree drivers do this as well, so do
it for all three types of chips.
Tested with RTL8811CU (Tenda U9 V2.0).
