[alsa-devel] [PATCH] ASoC: rt5640: Add RT5642 ACPI ID for Intel Baytrail

Asus T100TAF uses ACPI ID "10EC5642" for its audio codec. I suppose it is
updated ACPI ID for the RT5642 codec since some earlier platforms are using
"10EC5640" with the RT5642 too.

ACPI ID found from the DSDT table of Asus T100TAF. This makes the rt5640
codec driver probing but the audio itself is not working due a bit different
ACPI data and perhaps HW differences too compared to for instance Asus
T100TA.
