Abel Vesa 79536013a3 usb: Rename SPL_USB_SUPPORT to SPL_USB_STORAGE
Since there is the SPL_USB_HOST_SUPPORT for enabling USB support in SPL,
makes more sense to rename the SPL_USB_SUPPORT as SPL_USB_STORAGE.
Everything that is not part of the usb storage support in SPL is now
build under SPL_USB_HOST_SUPPORT.
