[PATCH] phy: omap-usb2-phy: Drop usage of "ti, dis-chg-det-quirk" DT property

"ti,dis-chg-det-quirk" property is not part of Linux kernel DT binding
documentation.  Therefore drop this and instead use soc_device_match()
to distinguish b/w AM654 SR1.0 and SR2.0 devices similar to Linux kernel
driver.
