mmc: omap_hsmmc: do not embed struct mmc in struct omap_hsmmc_plat

Browse Source 
The area for struct mmc can be allocated dynamically. It greatly reduces
the size of struct omap_hsmmc_plat. This is useful in cases where the board
level code declares one or two struct omap_hsmmc_plat because it doesn't
use the Driver Model.

This saves around 740 bytes for the am335x_evm SPL.
