mb/google/cyan: Adjust CID for realtek audio codec
Adjust CID to allow for Realtek's Windows drivers to attach
without breaking functionality under Linux.
Both Linux and Windows use ACPI HID/CID matching for driver attachment.
Since the Realtek 5650 isn't used in standard Windows laptops, the
'10EC5650' HID/CID isn't contained in the Windows drivers' lookup file
(.inf), but a catch-all 'INTCCFFD' entry does exist, so concatenate
that to the existing CID to allow the drivers to attach.
Test: build/boot google/edgar, verify working audio under
both Windows 10 (with Realtek drivers 10.0.10586.4393) and Linux
(GalliumOS 3.1 / kernel 4.16.18, Manjaro 18.1 / kernel 5.1.x)
