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
