Comment # 48 on bug 60802 from Anthony Waters

I looked into this a little bit and the issue appears to be within
evergreen_dma_copy_tile within evergreen_state.c.  It looks like when bank_h is
0 it causes the texture to appear bad, but bank_h is allowed to be 0 so I
believe the lines
cs->buf[cs->cdw++] = (detile << 31) | (array_mode << 27) |
                    (lbpp << 24) | (bank_h << 21) |
                    (bank_w << 18) | (mt_aspect << 16);
have the incorrect offsets, but I'm not 100% sure at the moment.
