There are currently many places that define the list of all Tegra GPIOs;
the DT binding header and custom Tegra-specific header file gpio.h. Fix
the redundancy by replacing everything with the DT binding header file.

Add a comment block to the top of each generated Tegra pinmux header file
indicating that the file was auto-generated, should not be manually
edited, and with a pointer to the tool and command used to generate it.

Enable the I2C3 pins so that the TPM can be used.
Note: There is an DP change also, caused by running board-to-uboot.py
script in the latest tegra-pinmux-script tree.

We need to turn on all audio-related clocks for the Chrome OS kernel to
boot. Otherwise it will hang when trying to enable audio.
Also for Linux set up graphics driver video protection.

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

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.
