8e593a223e phy: renesas: phy-rcar-gen3-usb3: Convert to platform remove callback returning void 
The .remove() callback for a platform driver returns an int which makes
many driver authors wrongly assume it's possible to do error handling by
returning an error code. However the value returned is (mostly) ignored
and this typically results in resource leaks. To improve here there is a
quest to make the remove callback return void. In the first step of this
quest all drivers are converted to .remove_new() which already returns
void.

Trivially convert this driver from always returning zero in the remove
callback to the void returning variant.

7c7356bab8 phy: rcar-gen3-usb3: add support for R-Car Gen3 USB 3.0 PHY 
The USB 3.0 PHY modules of R-Car Gen3 SoCs have:
 - Spread spectrum clock (ssc).
 - Using USB 2.0 EXTAL clock instead of USB 3.0 clock.
 - Enabling VBUS detection for usb3.0 peripheral.

So, this driver supports these features.
