If enable Mediatek 8173 SoC, it should also enable power domain
driver. Otherwise access clk subsystem register will fail.

MT8173 clk driver is enabled by default, but power domain driver
is not. If MM subsystem power on, mm_sel topckgen mux is off,
then access any MM subsystem register will cause system hang. Enable
SCPSYS driver to make sure both MM subsystem power and mm_sel to
on/off together to avoid system hang.
This patch fix current linux-next mt8173-evb boot to shell fail
problem.
