> The Xilinx XPS USB host controller is legacy soft IP for PPC405 and
> MicroBlaze FPGA designs.
> 
> This IP core relies on Xilinx Platform Studio (XPS) and the ISE Design
> Suite, both of which were discontinued by Xilinx years ago. Furthermore,
> modern AMD toolchains (Vivado Design Suite and Vitis) provide no support
> for the legacy PLB (Processor Local Bus) architecture used by this core.
> As a result, no new hardware designs can be built using this IP.
> 
> Nothing in the upstream tree carries its "xlnx,xps-usb-host-1.00.a"
> compatible string and no defconfig enables CONFIG_XPS_USB_HCD_XILINX.
> The compatible was never documented in a schema binding.
> 
> It is also one of the few remaining users of the deprecated glue model
> where the .c file is #included into ehci-hcd.c rather than built as its
> own object.
> 
> Given the complete obsolescence of the supporting hardware development
> tools and the lack of upstream users, remove the dead driver.
