If enable Mediatek 8173 SoC, it should also enable power domain
driver. Otherwise access clk subsystem register will fail.
Signed-off-by: Eddie Huang <eddie.huang@mediatek.com>

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.

This gets the mt8173-evb booting again with arm-soc/for-next and
mainline for me.
I'll let Matthias queue this up and send it with any other fixes for
v4.4-rc1.
Thanks for the fix,
Kevin
P.S. it's curious that nobody caught this basic boot failure before. Is
nobody else testing mainline on this board? or maybe not using the
upstream defconfig?

Matthias, this is still broken in arm-soc. Curious if your planning
on sending a fix? If you prefer, with your ack, we can apply directly
to arm-soc/fixes.
