sm5803: Enable BFET when disabled
When coming out of cutoff, the BFET can be disabled if the system is
powered up from an auxiliary charge port and the battery is dead. Our
attempts to regulate VSYS won't actually cause the battery to come out
of cutoff. This commit adds a check to see if the BFET is disabled
and tries to enable it such that the battery can actually be charged.
BUG=b:168730125, b:168135339
BRANCH=None
TEST=Build and flash drawcia, cutoff battery, wait 15s, plug in AC on
C1, verify that DUT is able to revive battery pack and start charging.
Verify that this works at 0% SoC and 50%.
