mailbox: mtk-cmdq: Add cmdq private data to cmdq_pkt for generating instruction
Add the cmdq_mbox_priv structure to store the private data of GCE,
such as the shift bits of the physical address. Then, include the
cmdq_mbox_priv structure within the cmdq_pkt structure.
This allows CMDQ users to utilize the private data in cmdq_pkt to
generate GCE instructions when needed. Additionally, having
cmdq_mbox_priv makes it easier to expand and reference other GCE
private data in the future.
Add cmdq_get_mbox_priv() for CMDQ users to get all the private data
into the cmdq_mbox_priv of the cmdq_pkt.
