[Mesa-dev] [PATCH v2 4/5] ac: remove amdgpu.h dependency

[Emil Velikov]

From: Emil Velikov <emil.velikov at collabora.com>

Add a couple of forward declarations and drop the amdgpu.h requirement.

With this we can build the r300 and r600 drivers without the need for
amdgpu.

v2:
 - Add amdgpu.h include in the C file (Marek)
 - Add a comment about pre C11 typedef redeclaration warning (Eric)
