[PATCH 12/16] ASoC: SOF: amd: wire signed firmware load callback for ACP7x via ACPI

[Vijendar Mukunda <Vijendar.Mukunda@amd.com>]

Read ACPI property acp-sof-signed-firmware-image in sof_acp7x_ops_init()
and register acp_sof_load_signed_firmware as the load_firmware callback
only when the property is set.
