usb: phy: snps: Put PHY in non-driving mode for charger detection
PMIC charger driver requests PHY to place USB D+/D- lines in hi-Z
state prior to performing charger detection. This is exposed as a
regulator interface. During the enable callback, perform power on
and reset of the PHY and then write to the UTMI override register
to set OPMODE as non-driving.
In the event that a host downstream port is connected, the normal
init sequence will follow and OPMODE will be set to normal due to
the reset.
