[PATCH v2 0/4] Devicetree support for Glymur GPU

[Akhil P Oommen <akhilpo@oss.qualcomm.com>]

This series adds the necessary Device Tree bits to enable GPU support
on the Glymur-based CRD devices. The Adreno X2-85 GPU present in Glymur
chipsets is based on the new Adreno A8x family of GPUs. It features a new
slice architecture with 4 slices, significantly higher bandwidth
throughput compared to mobile counterparts, raytracing support, and the
highest GPU Fmax seen so far on an Adreno GPU (1850 Mhz), among other
improvements.

This series includes patches that updates DT schema, add GPU SMMU &
GPU/GMU support. Keen-eyed readers may notice that the zap shader node
is missing. This is intentional: The Glymur-based laptop platforms
generally allow booting Linux at EL2 (yay!), which means the zap firmware
is not required here.

There is an update to the gxclkctl/drm drivers to properly support the IFPC
feature across all A8x GPUs. That series [1] is necessary to properly
support Glymur GPU:

Just FYI, on top of the linux-next, I had to pick below series [2] to boot
the device properly. But it is unrelated to GPU or this series:

Changes in v2:
- Keep GPU/GMU enabled by default and drop the enablement patch (Konrad)
- Drop zap shader node from DT
- A new patch to update GPU SMMU dt schema.
- Adjust reg range in dt nodes to avoid overlap. 
- Removed cx_dbgc range as it is already stable across chipsets. This
  region is now part of kgsl_3d0_reg_memory range.
