Driver: BD99955: Use Charger interrupt to detect VBUS activity
Added support to enable the BD99955 charger interrupt to detect
the VBUS activity. With this approach GPIO USB_Cx_VBUS_DET_N pin
can be removed.
BUG=chrome-os-partner:53688
BRANCH=none
TEST=Manually tested on Amenia. Type-C, DCP & SDP chargers can
negotiate to desired current & voltage. Battery can charge.
USB3.0 & USB2.0 sync devices are detected by the Kernel.
