There is a Vivante GC1000 (v5037) in LS2K1000 and LS7A1000, this GPU is a
PCI device, and it has 2D and 3D cores in the same core. Thus, this patch
set is trying to add PCI device driver support to etnaviv.

v6:
	* Fix build issue on system without CONFIG_PCI enabled
v7:
	* Add a separate patch for the platform driver rearrangement (Bjorn)
	* Switch to runtime check if the GPU is dma coherent or not (Lucas)
	* Add ETNAVIV_PARAM_GPU_COHERENT to allow userspace to query (Lucas)
	* Remove etnaviv_gpu.no_clk member (Lucas)
	* Various Typos and coding style fixed (Bjorn)
