[PATCH] Revert "mmc: davinci: drop struct davinci_mmc_plat"

[Tom Rini <trini@konsulko.com>]

Adam Ford reports that this change breaks booting on da850-evm and
Bartosz Golaszewski agrees that with the impending release we should
revert the change for now.  With that noted:

This reverts commit 21a4d80a710c79053ac1deaa65ff9b69e6c031d4.
