Yoshihiro Shimoda 2acecd5896 usb: renesas_usbhs: Fix UGCTRL2 value for R-Car Gen3 
The latest HW manual (Rev.0.55) shows us this UGCTRL2.VBUSSEL bit.
If the bit sets to 1, the VBUS drive is controlled by phy related
registers (called "UCOM Registers" on the manual). Since R-Car Gen3
environment will control VBUS by phy-rcar-gen3-usb2 driver,
the UGCTRL2.VBUSSEL bit should be set to 1. So, this patch fixes
the register's value. Otherwise, even if the ID pin indicates to
peripheral, the R-Car will output USBn_PWEN to 1 when a host driver
is running.
