mfd: Add phoenix lite (twl6025) support to twl6030 

Phoenix Lite is based on the twl6030 family of PMICs. It has mostly the
same feature set of twl6030 but with small changes. The codec block has
also been removed. It also has a new charger block and new features in
its ADC block. VUSB handling also differs.
