Testing of [1] pointed out that on all modern Qualcomm platforms GPU
clock controller shares regiser space with the GMU. All gpucc drivers
use (internally) devm_platform_ioremap_resource(), preventing the GPU
driver from using devm_ioremap_resource() on its own. As GMU register
space includes gpucc's one, make gpucc drivers use non-requesting
helper, allowing GPU to take over the bigger memory region.
