USB: phy: Add support to invoke DP and DM sourcing and pulsing
This change adds support for sourcing and pulsig with DP/DM
using QUSB PHY. This change uses POWER_SUPPLY_PROP_DP_DM power
supply property with different values to achieve the same.
This change is a cherry-pick of msm-3.18 commit
55b93e2506d5399b1b0ee4a1b173168fb8026548 ("USB: Add support to
invoke DP and DM sourcing and pulsing") with only the change
from include/linux/usb/phy.h
