With the new device-tree rules it is possible to put device-tree changes
needed by U-Boot into their own file. As an example of this approach, move
Tegra over to use it.

Apparently the unit address in a DT node name is now supposed to be a
single integer value, rather than a comma-separated list of individual
cell values. Fix the U-Boot DTs to comply with this naming convention.

The Tegra MMC driver currently honors "sdhci" entries in /aliases. The
MMC core however uses "mmc" entries in /aliases. This difference will be
relevant once the Tegra MMC driver is converted to DM, and the MMC core
handles alias lookups. To avoid issues during that conversion, fix the
Tegra MMC driver and all Tegra DTs to use the same alias name as the MMC
core does.

Sync up these files with Linux v4.4. Some differences remain, principally
that the addresses are still 32-bit in U-Boot.

Enable the EC and keyboard, using the SPI bus.
The EC driver requires a particular format and a deactivation delay. Also
U-Boot does not support interrupts.
For now, adjust the device tree to comply. At some point we should tidy
this up to support interrupts and make tegra and exynos use the same setup.

Add required setup for the LCD display, and a function to provide the
board ID. This requires GPIOs to be available prior to relocation.

These are needed to enable the USB bus (although not sufficient since it
still does not work).

Nyan-big is a Tegra124 clamshell board that is very similar to venice2, but
it has a different panel, the sdcard cd and wp sense are flipped, and it has
a different revision of the AS3722 PMIC.
This is the Acer Chromebook 13 CB5-311-T7NN (13.3-inch HD, NVIDIA
Tegra K1, 2GB). The display is not currently supported, so it should
boot on other nyan-based Chromebooks also, but only the device tree for
nyan-big is provided here.
The device tree file is from Linux but with features removed which are
unlikely to be supported in U-Boot soon (regulators, pinmux). Also the
addresses are updated to 32-bit.

(rebase, change to 'nyan-big', fix pinmux that resets nyan-big)
