For the Secure Video Path (SVP) feature, inculding the memory stored
secure video content, the registers of display HW pipeline and the
HW configure operations are required to execute in the secure world.

So using a CMDQ secure driver to make all display HW registers
configuration secure DRAM access permision settings execute by GCE
secure thread in the secure world.

We are landing this feature on mt8188 and mt8195 currently.
