From: AngeloGioacchino Del Regno <angelogioacchino.delregno@xxxxxxxxxxxxxx> [ Upstream commit 8f03c30cb814213e36032084a01f49a9e604a3e3 ] The PC_DBG_ECO_CNTL register on the Adreno A5xx family gets programmed to some different values on a per-model basis. At least, this is what we intend to do here; Unfortunately, though, this register is being overwritten with a static magic number, right after applying the GPU-specific configuration (including the GPU-specific quirks) and that is effectively nullifying the efforts. Let's remove the redundant and wrong write to the PC_DBG_ECO_CNTL register in order to retain the wanted configuration for the target GPU.
