dfu: mmc: Provide support for eMMC boot partition access
Before this patch it was only possible to access the default eMMC HW partition. By partition selection I mean the access to eMMC via the ext_csd[179] register programming. It sometimes happens that it is necessary to write to other partitions. This patch adds extra attribute to "raw" sub type of the dfu_alt_info environment variable (e.g. boot-mmc.bin raw 0x0 0x200 mmcpart 1;) It saves the original boot value and restores it after storing the file.
