From: Viswanath Puttagunta <vishp@xxxxxx>
The charger detection module is getting
disabled during boot up if a DCP (Dedicated charging port)
is connected before device is powered on (Bit 30 of CONTROL_USB2PHYCORE
is set). This patch enables charger type detection each time the charger type
wants to be detected.
