usb: phy: Expose new PHY callback for performing PHY reset
Add a new PHY callback for performing PHY reset, which is required
by some targets during their initialization sequence.
As usb_phy_reset name was already in use by local msm PHY APIs,
change the previous usb_phy_reset to msm_usb_phy_reset.
