[Intel-gfx] Significance of Golden context

[Siluvery, Arun]

Hi,

Could someone explain the significance of Null context/Golden state?
I understand we are initializing 3D state in this batch and we send this 
at the beginning to start the HW with a known state but what are 
implications of not doing this? what kind of issues we can expect if we 
don't do this? How is this golden state determined?

As a test I disabled this for Gen8 and I can boot Android without any 
issues.

regards
Arun
