mmc: Fixes for Dual Data Rate (DDR) support
The DDR support patch needs the following fixes:
- The block driver does not need to know about DDR, any more
than it needs to know about bus width.
- Not only the card must be switched to DDR mode. The host
controller must also be configured, which is done through
the 'set_ios()' function.
- Do not set the DDR mode state until after the switch command
is successful.
- Setting block length is not supported in DDR mode. Make that
a core function and change the other place it is used (mmc_test)
also.
