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.
