[GIT PULL] etnaviv-next for 4.15

[Lucas Stach]

Hi Dave,

this time around we have a bunch more patches, compared to the last
cycles.

Most notable addition this time is the support for the GPU performance
counters by Christian. This has been in the making for some time and it
has matured a lot. Since this is adding UAPI, the corresponding WIP
userspace can be found at [1] mesa/libdrm repos. I expect that
Christian sends out the final userspace patches for this once you have
pulled the kernel bits.

Philipp optimized the probe path, so etnaviv gets out of the way for
systems that want to boot real quick.

I've done mostly cleanups, disentangling etnaviv from the IOMMU API,
with some MMUv1 optimizations on the way.

Regards,
Lucas
