It changes the HTILE (HyperZ) allocation function to
r600_aligned_buffer_create. Without that, the hardware can hang on big GPUs
(Tahiti/Pitcairn/Hawaii/Tonga/etc), but not APUs or small GPUs. The hang
happens when TTM decides to move HTILE to a different location with an
unaligned physical address (which is pretty random). The hardware tries to
access the unaligned address and boom.
