[U-Boot] [PATCH v5 04/12] dfu: mmc: raw data write fix

[Lukasz Majewski]

Hi Mateusz,

> When user attempted to perform a raw write using DFU (vide
> dfu_fill_entity_mmc) with MMC interface not initialized before,
> get_mmc_blk_size() reported invalid (zero) block size - it wasn't
> possible to write ie. a new u-boot image.
> 
> This commit fixes that by initializing MMC device before use in
> dfu_fill_entity_mmc().
> 
> While fixing initialization sequence, I had to change about half of
> dfu_fill_entity_mmc's body, so I refactored it on the way to make it,
> IMHO, considerably more comprehensible.
> 
> Being left as dead code, get_mmc_blk_size() was removed.
> 
> Tested on Samsung Goni.
