From: Alex Deucher <alexander.deuc...@amd.com>
Add a flag for when allocating a context to flag it as
secure. The kernel driver will use this flag to determine
whether a rendering context is secure or not so that the
engine can be transitioned between secure or unsecure
or the work can be submitted to a secure queue depending
on the IP.
v2: the flag will be used for security, so remove the comment (Ray)
