Currently we're only deasserting REG_A6XX_RBBM_GBIF_HALT, but we also need REG_A6XX_GBIF_HALT to be set to 0. For GMU-equipped GPUs this is done in a6xx_bus_clear_pending_transactions(), but for the GMU-less ones we have to do it *somewhere*. Unhalting both side by side sounds like a good plan and it won't cause any issues if it's unnecessary. Also, add a memory barrier to ensure it's gone through.
