The signed_fw_image member of struct sof_amd_acp_desc is used to enable signed firmware support in the driver via the acp_sof_quirk_table. In preparation to support additional use cases of the quirk table (i.e. adding new flags), move signed_fw_image to a new struct acp_quirk_entry and update all references to it accordingly. No functional changes intended.
