mainboard/google/reef: fill in NHLT ACPI OEM header fields

Fill in the NHLT ACPI OEM header fields to differentiate
different audio solutions on a per board basis. This handles
boards that share a firmware that are differentiated by
the SKU id and boards that have their own firmware. For the
latter, the Oem Table ID uses the VARIANT_DIR to differentiate.
"reef" is always used for Oem ID which is treated as more of
family in this case.

iasl -d shows the following on reef:
[00Ah 0010   6]                       Oem ID : "reef"
[010h 0016   8]                 Oem Table ID : "reef"
[018h 0024   4]                 Oem Revision : 00000008
