drm/v3d: Define the fourcc modifier for the Broadcom UIF format.

/* Broadcom UIF format

 *

 * This is the common format for the current Broadcom multimedia

 * blocks, including V3D 3.x and newer, newer video codecs, and

 * displays.

 *

 * The image consists of utiles (64b blocks), UIF blocks (2x2 utiles),

 * and macroblocks (4x4 UIF blocks).  Those 4x4 UIF block groups are

 * stored in columns, with padding between the columns to ensure that

 * moving from one column to the next doesn't hit the same SDRAM page

 * bank.

 *

 * To calculate the padding, it is assumed that each hardware block

 * and the software driving it knows the platform's SDRAM page size,

 * number of banks, and XOR address, and that it's identical between

 * all blocks using the format.  This tiling modifier will use XOR as

 * necessary to reduce the padding.  If a hardware block can't do XOR,

 * the assumption is that a no-XOR tiling modifier will be created.
