[PATCH 6.8 666/715] ASoC: SOF: amd: Move signed_fw_image to struct acp_quirk_entry

From: Cristian Ciocaltea <cristian.ciocaltea@collabora.com>

[ Upstream commit 33c3d813330718c403a60d220f03fbece0f4fb5c ]

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.
