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.
