usb: gadget: udc: renesas_usb3: Fix soc_device_match() abuse
[ Upstream commit cea45a3bd2dd4d9c35581328f571afd32b3c9f48 ]
soc_device_match() is intended as a last resort, to handle e.g. quirks
that cannot be handled by matching based on a compatible value.
As the device nodes for the Renesas USB 3.0 Peripheral Controller on
R-Car E3 and RZ/G2E do have SoC-specific compatible values, the latter
can and should be used to match against these devices.
This also fixes support for the USB 3.0 Peripheral Controller on the
R-Car E3e (R8A779M6) SoC, which is a different grading of the R-Car E3
(R8A77990) SoC, using the same SoC-specific compatible value.
Fixes: 30025efa8b5e75f5 ("usb: gadget: udc: renesas_usb3: add support for r8a77990")
Fixes: 546970fdab1da5fe ("usb: gadget: udc: renesas_usb3: add support for r8a774c0")
