ENGR00315499-6 ARM:imx6: Add USB gadget driver imx_udc to support Android fastboot
Android fastboot leans on the USB gadget driver to communicate with host. Porting
the imx_udc driver from v2009.08 with two changes: adding resource/memory release
APIs and replacing the uncached memory with cache flush&invalidate operations.
Pins and Clocks initialization are added to support boards:
mx6qdlsabresd, mx6qdlsabreauto, mx6slevk
