sc7180: Decouple the switchcap control from the power sequence
Currently, SC7180 power sequence is tightly coupled with a single
switchcap part, i.e. DA9313. Should decouple the switchcap control
from the power sequence, such that more different switchcap parts
can be supported.
BRANCH=None
BUG=b:163867792
TEST=Built the affect images and booted into kernel.
