stm32mp: stm32prog: add support of boot partition for eMMC device

Browse Source 
Add support of eMMC device boot partition with
part_id = -1 for offset="boot1"
     or = -2 for offset="boot2"

The stm32prog command configures the MMC DFU backend with "mmcpart"
and configure the eMMC (command "mmc bootbus" and "mmc partconf")
when the update is done.
