usb: msm_otg: Add support for vdd min without phy retention

As a part of usb disconnect, usb will be put into low power mode
by putting phy into retention, voting for xo shutdown and vdd
minimization, also turning off LDOs. But on 8x10 platform,turning
off regulators is causing leakage current due to hardware limitation.
Hence add support for vdd minimization without putting phy into
retention to prevent power consumption. Also disable id pull up
as recommended by hardware team.
