From: Ville Syrjälä <ville.syrjala@xxxxxxxxxxxxxxx>
Start using the kms crtc index rather than the pipe almost
everywhere. The two numbers could in theory be different
if the hardware has some pipes fused off. Though I think
such non-contiguous fusing won't actually happen on the
hardware generations the driver fully supports.
The places where using the kms crtc index is the correct
choice have to do with the vblank ioctl crtc selection.
The only place where we must stick to the hardware pipe
indexing is the MI_SCANLINE_WAIT stuff as there we have to
construct CS packets to be consumed by the hardware itself.
