-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").

-Greg/Mathias: I'm not sure if it's more like USB subsystem stuff or xHCI
-Could you decide which one of you could pick that, please?

-V2: Drop useless "default n", thanks Sergei :)

-+	  Adds an xHCI host driver for a generic platform device, which
-+	  provides a memory space and an irq.
-+	  It is also a prerequisite for platform specific drivers that
