The way that struct mmc was implemented was a bit of a mess;
configuration and internal state all jumbled up in a single structure.
On top of that the way initialization is done with mmc_register leads
to a lot of duplicated code in drivers.
Typically the initialization got something like this in every driver.
struct mmc *mmc = malloc(sizeof(struct mmc));
memset(mmc, 0, sizeof(struct mmc);
/* fill in fields of mmc struct */
/* store private data pointer */
mmc_register(mmc);
By using the new mmc_create call one just passes an mmc config struct
and an optional private data pointer like this:
struct mmc = mmc_create(&cfg, priv);
All in tree drivers have been updated to the new form, and expect
mmc_register to go away before long.
Changes since v1:
* Use calloc instead of manually calling memset.
* Mark mmc_register as deprecated.

Added support for MMC/SD cards for Davinci. This feature is enabled by
CONFIG_DAVINCI_MMC and is dependant on CONFIG_MMC and CONFIG_GENERIC_MMC
options. This is tested on DM355 and DM365 EVMs with both the available mmc
controllers.
