Rob Clark ba7454a155 dri2+gallium: Support to import suboptimal formats ...

In some cases a format may be supported in a more limited way by the
hardware.  For example, formats with NPoT pixel sizes.  A driver might
normally prefer that mesa/st use R8G8B8X8 rather than R8G8B8.  But if
the user wants to (dma-buf/etc) import R8G8B8, it is still possible,
and in this case zero copy is more important.

So add a PIPE_BIND_x flag as a hint to the driver when checking if
a format is supported.
