[PATCH] usb: gadget: i.MX: Move PBL USB gadget driver to arch/

[Sascha Hauer]

The i.MX PBL USB gadget driver is currently selected by architecture
Kconfig options. When USB gadget support is disabled then the build
system doesn't descend into the directory where the driver is, leading
to undefined references. We could change that and descend into the
directory unconditionally, but as the driver doesn't have any
dependencies to the USB gadget framework we can also move the driver
to arch/arm/mach-imx/ to solve this problem.
