===============

[ Upstream commit 6c05cb145d6716f00d452aeb27916efb6d190cca ]

Right now xhci-plat-hcd can be built when using one of platform specific
drivers only (mvebu/rcar). There shouldn't be such limitation as some
platforms may not require any quirks and may want to just use a generic
driver ("generic-xhci" / "xhci-hcd").
