fastboot: add command to select the default emmc hwpart for boot
Add fastboot command oem partconf which executes the command ``mmc partconf <id> <arg> 0`` on the current <id> mmc device to configure the eMMC boot partition with <arg>: boot_ack boot_partition, so the command is: $> fastboot oem partconf:<boot_ack> <boot_partition> The partition_access argument is forced to 0 (userdata) Signed-off-by: Patrick Delaunay <patrick.delaunay@foss.st.com> [lukma - Kconfig adjustments after merging this patch]
