Dependency of USB_DWC3_XILINX on ARCH_VERSAL

[Lukas Bulwahn]

Dear Manish,

Commit 84770f028fab ("usb: dwc3: Add driver for Xilinx platforms")
adds the config USB_DWC3_XILINX, which depends on the config
ARCH_VERSAL. However, the config ARCH_VERSAL is not defined in the
current mainline kernel repository.

Will a definition of ARCH_VERSAL follow eventually (soon?) for
mainline, is there just a further out-of-tree development for which
the dependency is useful or is this just a mistake and can be
corrected?

Best regards,

Lukas
