freedreno/common: set up a830 properties

Browse source 
Adjust or fill out various properties for the a830 GPU, setting up a gen1
base. So far these mostly mirror the gen2 properties, except for gmem
config layouts, and they will probably further diverge down the line.

A new GPU ID for a830 is also added, Turnip there runs on top of KGSL.
