Enables the gpio-base mic detection on the Acer Chromebook 13. This
gpio is set by the jack-detection chip when it notices either of the
TRRS type headsets with a microphone.

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.
