The sram property was incorrectly added to the GMU binding when it
really belongs with the GPU binding instead. Let's go ahead and
move it.
While changes are being made here, let's update the sram property
description to mention that this property is only valid for a3xx and
a4xx GPUs. The a3xx/a4xx example in the GPU is replaced with what was
in the GMU.

Background thread:

I started to look at what it would take to convert the GPU bindings to
YAML, however I am unsure of the complete list of "qcom,adreno-XYZ.W"
compatibles that are valid.

Thank you kindly! I'll re-submit my stack on top of this.

heh, I'm not sure anyone is ;-)
That said, adreno_device.c should give a complete list of XYZ (and
*usually* the .W doesn't matter too much)
