USB: msm_otg: Fix a bug in charger detection procedure

USB PHY is put into non-driving mode and pull-down resistors on DP
and DM are disabled before starting the charger detection.  The
PHY is put into driving mode at the end of the charger detection
without enabling the pull-down resistors.  Due to this DP is
pulled high when a dedicated charger is connected.  USB controller
is not allowing PHY suspend if line state is non-zero when charger
is connected.  Enable pull-down resistors at the end of charger
detection to resolve this issue.

usb: dwc3: Set the hsphy init value for usb host mode

host mode doesn't work correctly due to eye diagram tuning for usb peripheral.
So set the its own hsphy init value int the usb host mode.
