[PATCH 5.10 033/141] Revert "usb: gadget: udc-xilinx: replace memcpy with memcpy_toio"

[Greg Kroah-Hartman]

From: Greg Kroah-Hartman <gregkh@xxxxxxxxxxxxxxxxxxx>

[ Upstream commit fe0a2ac7c627b064c479ad0c3b25e531d342e048 ]

This reverts commit 8cb339f1c1f04baede9d54c1e40ac96247a6393b as it
throws up a bunch of sparse warnings as reported by the kernel test
robot.
