What does this MR do and why?
anv: update batch chaining to Gfx9 commands
I don't know this fixes anything but I noticed the generated draws jump into addresses slightly different from CPU generated jumps.
After checking the genxml, I noticed MI_BATCH_BUFFER_START "Batch Buffer Start Address" fields have different sizes in Gfx8 & Gfx9+.
