Subject: usb: gadget: mv_udc_core: fix phy_regs I/O memory leak

From: Alexey Khoroshilov <khoroshilov@ispras.ru>

commit 53e20f2eb161fbe9eea28b54dccc870cec94eca2 upstream.

There was an omission in transition to devm_xxx resource handling.
iounmap(udc->phy_regs) were removed, but ioremap() was left
without devm_.
