U-boot: MMC update.
MMC has been updated with several improvements. Primarily MMC
performance has been improved by using assembler code for low
level FIFO handling. Also some MMC functionality has been added,
e.g. support for DDR and reliable write.
Data and command delay times were incremented, otherwise hangups and
timeouts were observed.
Tested on HREF+ 1.1 V21 and HREF+ 1.1 V32 (Micron PoP).
Following WP depends on this change (more reliable SD card write
support):
