[Mesa-dev] [PATCH 2/2] intel/toosl/aubwrite: Always use physical addresses for traces.

[Rafael Antognolli]

It looks like we can't rely on the simulator to always translate virtual
addresses to physical ones correctly. So let's use physical everywhere.

Since our current GGTT maps virtual to physical addresses in a 1:1 way,
no further changes are required.

Additionally, we have other address spaces not in use right now. So
let's make it easier to switch which one we are using by putting the
default one into the aub_file struct.
