Update xf86-video-amdgpu to 1.1.0

I'm pleased to announce the 1.1.0 release of xf86-video-amdgpu, the Xorg
driver for AMD Radeon GPUs supported by the amdgpu kernel driver.
This release supports xserver versions 1.9-1.18.

Highlights:

* Support for the upcoming Polaris family of GPUs.
* Option "TearFree" can now prevent tearing with rotation/reflection as
  well (with Xorg >= 1.16).
* RandR CRTC transforms now work correctly (but for now still exhibit
  tearing even with TearFree).
* The RandR 1.4 provider name is now no longer hardcoded to "amdgpu"
  but constructed from the GPU chipset name and bus ID, allowing
  several GPUs supported by this driver to be distinguished by name.
* The RandR primary output is now always explicitly marked as such.
* The driver can prevent clients trying to use the DRI3 extension over a
  display connection forwarded via SSH from hanging.
* VDPAU/OpenGL interoperation can now work with DRI3 enabled.
* Many more fixes for issues using the DRI3/Present extensions.

Plus many other small improvements and fixes. Thanks to everybody who
contributed to this release in any way!
