mailbox: mtk-cmdq: Add driver data to support for MT8196 



MT8196 has 2 new hardware configuration compared with the previous SoC,
which correspond to the 2 new driver data:

1. mminfra_offset: For GCE data path control
   Since GCE has been moved into mminfra, GCE needs to append the
   mminfra offset to the DRAM address when accessing the DRAM.

2. gce_vm: For GCE hardware virtualization control
   Currently, the first version of the mt8196 mailbox controller only
   requires setting the VM-related registers to enable the permissions
   of a host VM.
