SM5803: Prevent brown out on source disable
The PD tasks will disable sourcing on initial boot up. This can cause
the SM driver to clear sinking mode, while attempting to clear the
sourcing related bits. This change skips disabling source mode if sink
mode is currently present. Additionally, it skips the Vbus ramp up wait
which enable requires.
BRANCH=None
BUG=b:168931726
TEST=on waddledee, confirm booting with a battery doesn't brown out with
either port. Confirm that FLOW1 is set to zero when sinking dongle is
unplugged.
