[GIT PULL] etnaviv-next for 4.9

[Lucas Stach]

Hi Dave,

this is the etnaviv feature pull-request for Linux 4.9.

Notable changes:

- Cleanups from Fabio to some error paths and proper error propagation.

- Lots of refactoring and new code to support the new MMU version 2,
still relatively unoptimized and doesn't yet provide better process
isolation than MMUv1, but enough to get newer cores up and running.

- New hardware support: GC3000, as found on the NXP i.MX6 QuadPlus SoC.

Regards,
Lucas
