This corrects the pinmux for accessing the TPM over the I2C line. Thus,
it allows correctly probing the module, that previously failed with I2C
errors.

Depthcharge (the payload used with cros devices) will attempt to detect
boards using their revision. This includes all the known revisions for
the nyan-big board so that the dtb can be selected preferably.
Defining compatibly revisions allows depthcharge to select the kernel
via the revision it detects instead of using the default kernel. This
allows having a FIT image with multiple kernels for multiple devices.

Please keep the remaining 0, notation on the GPU node in place as a
former mainline U-Boot version was looking for that particular notation
in order to perform required fix-ups on it.

This adds a new file, tegra124-nyan-big-emc.dtsi that contains
valid timings for the EMC memory clock. The file is included to the
main device tree file for the Nyan Big.
The frequency 528MHz is missing because we don't currently have a timing
configuration that works.
Additionally, only the timings for the ram-code 1 is present as that's
what could be tested currently, though downstream has timings for more
ram-codes.

Google has submitted a board config for the pinmux programming of the
Nyan Big board. Use the whole of it as it's generated to make it easier
to update as the configuration gets fixed in the future.

Change it from "Acer Chromebook 13" to GoogleNyanBig so it's unique and
identifiable.
With this change the card id exposed to userspace becomes GoogleNyanBig
instead of the current A13.

There are general changes pending to make the /aliases/serial* entries
number the serial ports on the system. On Tegra, so far the ports have
been just numbered dynamically as they are configured so that makes them
change.
To avoid this, add specific aliases per board to keep the old numbers.
This allows us to change the numbering by default on future SoCs while
keeping the numbering on existing boards.

The Acer Chromebook 13, codenamed Big, contains an NVIDIA tegra124
processor and is similar to the Venice2 reference platform.
The keyboard, USB 2, audio, sdcard and emmc have been tested
and work on the 1366x768 models. The Full HD models haven't been
tested yet.
WiFi does not yet work, it needs at least some PMIC changes to enable
the 32k clock.
The elan trackpad is not yet functional but hopefully will be soon as
there are patches under review.
There is also an issue on reboot because the TPM isn't reset. It will
cause the stock firmware to enter recovery mode. This can be worked
around by an EC-reset, press the refresh and power keys at the same
time.
