Tested-by: Macpaul Lin <macpaul.lin@mediatek.com>

Test method: test build pass and boot pass based on 'for-next' branch.

N
ote:
System suspend and resume of MT8195 has not been ready or enabled
on mainline. We cannot verify USB Host remote wake-up on mainline code,
but the settings and function works when applied to MediaTek's internal
working tree.
