b3b9d7ca32 dm: tegra: cros_ec: Enable Chrome OS EC on Nyan-big
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.

0deba29c20 tegra: nyan-big: Add LCD PMIC init and board ID
Add required setup for the LCD display, and a function to provide the
board ID. This requires GPIOs to be available prior to relocation.

84786a4c58 dm: usb: tegra: Add vbus GPIOs for nyan
These are needed to enable the USB bus (although not sufficient since it
still does not work).

a6c7b46181 ARM: tegra: Add support for nyan-big board
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)
