drm/xe/vf: Boostrap all GTs immediately after MMIO init

Browse Source 
Currently we perform the bootstrap for the primary GT early on during
device init, while the media GT bootstrap happens when we try and fetch
the hwconfig table. For consistency, move the bootstrap of the media GT
happen at the same time as the primary GT, so that all the subsequent
code can rely on both GTs being in the same state.

v2: Also drop config query from min_guc_load since we now do it
    early (Michal)
