DRM formats are defined to be little-endian, unless the DRM_FORMAT_BIG_ENDIAN flag is set. Hence writes of multi-byte pixel values need to take endianness into account. Introduce a swap32() helper to byteswap 32-bit values, and a cpu_to_le32() helper to convert 32-bit values from CPU-endian to little-endian, and use the latter in the various pattern fill functions for 32-bit formats.
