SM5803: Share setting of FLOW_REG1 between tasks better
Both the OTG and charger driver set_mode functions in the sm5803 driver
could clear the CHG_EN bit. This change will only clear CHG_EN from a
specific call to inhibit charging, and otherwise operations will only
modify the bits they strictly need to modify.
Also added a mutex to indicate FLOW_REG1 is being changed since it can
be changed from both the charger and PD tasks.
BRANCH=None
BUG=b:153906171
TEST=on waddledee, able to source out of both ports and seeing somewhat
reduced boot looping without a battery
