[PATCH v2 1/2] ASoC: rt5645: Add support for Surface 3 tablet

[Stephen Just <stephenjust@gmail.com>]

* Add a dmi match for Surface 3
* Add ACPI match "10EC5640"

The Surface 3 tablet identifies the codec in ACPI as
10EC5640, but other devices use this identifier to match
the rt5640 codec. However, the probe code for each driver
will filter out mismatches.
