power_supply: Add type and properties for parallel charger 



USB Main charger type represents the main charging path. This will
be used to control charging parameters on the main charger.

FCC_DELTA property will be used to indicate whether hw implements
any FCC mitigation. This will be used to calculate the effective FCC
and set the FCC on the PMI.

PARALLEL_MODE property indicates whether the parallel charger chip is
configured in a mid-mid or usbin-usbin configuration.

ICL_REDUCTION property indicates by how much should the main charger
reduce its input current.
