[0/3] etnaviv softpin support

Message

Hi all,

this implements the last missing bits for softpin aka putting userspace
in charge of the GPU virtual address space. This builds on top of the
per-process address space series. As this is quite a stack of patches
now, I'm providing a git branch [1] with all the necessary patches.
Please note that I have not yet worked in the feedback I got for the
per-process address space patches.

The corresponding userspace bits can be found at [2]. The Mesa changes
always use softpin where possible and now finally allow GC7000 support
to work with a non-horrible UAPI interface.

Regards,
Lucas
