SM5803: Flow 1 register updates
This commit adds:
- bit names updated to the most recent SM5803A datasheet
- centralized control of FLOW1 updates after init in one function
- verification of charger register 0x5C contents before enabling
charging
- correction of init charger disable behavior
BRANCH=None
BUG=None
TEST=on drawcia, observe that sink mode is enabled when charger is
plugged in to MB, OTG bits are enabled with dongles plugged in
