From: Konrad Dybcio <konrad.dybcio@oss.qualcomm.com>

Add the GPU_CC and GX_CC (brand new! as far as we're concerned, this
is simply a separate block housing the GX GDSC) nodes, required to
power up the graphics-related hardware.

Make use of it by enabling the associated IOMMU as well. The GPU itself
needs some more work and will be enabled later.
