[PATCH v6 2/7] drm/mediatek/uapi: Add DRM_MTK_GEM_CREATE_RESTRICTED flag

[Jason-JH.Lin]

Add DRM_MTK_GEM_CREATE_RESTRICTED flag for the user space to tell the
kernel space this dma buffer is restricted.
The user space can store this flag into the private data of the dma
buffer after allocating.

A restricted buffer is used to store the secure video content to support
secure video path feature.
