phy: omap-usb2-phy: disable phy charger detect

AM654x PG1.0 has a silicon bug that D+ is pulled high after POR, which
could cause enumeration failure with some USB hubs.  Disabling the
USB2_PHY Charger Detect function will put D+ into the normal state.

Using property "ti,dis-chg-det-quirk" in the DT usb2-phy node to
enable this workaround for AM654x PG1.0.
