[U-Boot] [PATCH 3/6] fsl_dr_usb: Fixup disabled USB controllers nodes in device tree

[Anton Vorontsov <avorontsov@ru.mvista.com>]

We should add status = "disabled" property when USB controller can't
be used (for example when USB pins muxed away to another device).

Also convert whole fdt_fixup_dr_usb() to use more compact routines
from fdt_support.h.
