The files a3xx_gpu.c and a4xx_gpu.c have ifdefs for the OCMEM support
that was missing upstream. Add two new functions (adreno_gpu_ocmem_init
and adreno_gpu_ocmem_cleanup) that removes some duplicated code.

Commit eeb754746b14 ("drm/msm/gpu: use pm-runtime") adds a pointer
for the GPU platform device to the msm_gpu struct so we can
happily remove the same pointers from the individual GPU
structs.

Add support for adreno 330. Not too much different, just a few
differences in initial configuration plus setting OCMEM base.
Userspace support is already in upstream mesa.
Note that the existing DT code is simply using the bindings from
downstream android kernel, to simplify porting of this driver to
existing devices. These do not constitute any committed/stable
DT ABI. The addition of proper DT bindings will be a subsequent
patch, at which point (as best as possible) I will try to support
either upstream bindings or what is found in downstream android
kernel, so that existing device DT files can be used.

Add initial support for a3xx 3d core.
So far, with hardware that I've seen to date, we can have:
+ zero, one, or two z180 2d cores
+ a3xx or a2xx 3d core, which share a common CP (the firmware
for the CP seems to implement some different PM4 packet types
but the basics of cmdstream submission are the same)
Which means that the eventual complete "class" hierarchy, once
support for all past and present hw is in place, becomes:
+ msm_gpu
+ adreno_gpu
+ a3xx_gpu
+ a2xx_gpu
+ z180_gpu
This commit splits out the parts that will eventually be common
between a2xx/a3xx into adreno_gpu, and the parts that are even
common to z180 into msm_gpu.
Note that there is no cmdstream validation required. All memory access
from the GPU is via IOMMU/MMU. So as long as you don't map silly things
to the GPU, there isn't much damage that the GPU can do.
