cmd: mvebu/bubt: Add support for reading image from the SATA disk partition

Browse source 
This change allows to load boot image from the first SATA/SCSI device
partition and burn it to board boot location (e.g. SPI-NOR). This is
particularly when storage device is not handled by U-Boot as USB mass
storage (which is already supported by bubt) but as SATA/SCSI device.
