From: Stephen Warren <swar...@nvidia.com>
Implementations of the following functions are converted to use the new
standardized hooks: pin_mux_usb, pin_mux_spi, pin_mux_nand, pin_mux_mmc,
pin_mux_display. This simplifies the core board files.
For some boards, function sort order was changed so that functions appear
in they order they're called.
