power: supply: bq24190: Considers FORCE_20PCT when getting IPRECHG

Browse source 
Adds a check of the FORCE_20PCT bit when getting the precharge
current value.

According to the bit description for the FORCE_20PCT bit, when
FORCE_20PCT is true, the precharge current target is 50% of
what is configured in the IPRECHG bit field.
