Replace MMC/SD driver to fit new framework.

IR265772: MMC driver does not detect SDHC cards.

IR254201: Restructure MMC/SD driver for U8500 board according to the
block device framework in mainline U-Boot.

Changes to mmc framework:
- Multi Block Read support in mmc framework.
- Wrap Multi Block Write/Read to be able to adopt for large transaction.
- Removed incorrect check in EXT CSD for high capacity MMC.
- Corrected check for high capacity SD cards.
- Set MMC buswidth to 8, prio of using 4.

Known limitations/bugs in mmc framework:
- High capacity MMC, will likely not get the correct density.
- High speed is set, whether or not the host supports it or not.

board/st/u8500/mmc_utils:
IMPORTANT FOR DEVELOPERS:
- Removed unessary U-Boot commands which is already supported in
  cmd_fat.
- mmc_read_cmd_file: Read command.txt into bootcmd env from FAT FS in
  SD card.
- write_partition_block: Writes the MBR if it is not already written.

board/st/u8500/mmc_host[c.h]:
- Implements the entire MMC/SD host driver for the PL180 block.
- There is still room for optimization:
	Increase CLK-speed.
	Use  high-speed for SD cards.
	Is GPIO setup correctly for both cards an eMMC.
	EarlyDrop support not fully tested.
	Dynamically turn on voltage/clocks to SD, not always.
	More...

Note:
- Increased read/write performance for eMMC, to around 5.4 MB/s for
  sequential read/write. Earlier measurements was 3.5 MB/s for read and
  2.6 MB/s for write.
