phy: rockchip-inno-usb2: set floating charger type as DCP

Browse Source 
Floating charger is a kind of special USB charger that
dp/dm not shorted, which is incompatible with BC1.2 spec.

However, we need to support this floating charger, and
consider that the max charge current of floating charger
is the same as standard USB charger (dp/dm is shorted),
so we set the charger type as DCP for floating charger.
