nhlt: add api to override oem_id and oem_table_id of acpi_header_t
This patch added nhlt_soc_serialize_oem_overrides and
nhlt_serilalize_oem_overrides to be able to override oem_id and
oem_table_id.board file can pass specific string by calling
nhlt_soc_serialize_oem_overrides
kernel use these two fields to construct a topology binary name
if the designate file is not found a default dfw_sst.bin will be used
it is optional.
BUG=chrome-os-partner:49570
BRANCH=glados
TEST=Build & Booted kunimitsu board. Verified that kernel
can read new strings.
