In arch/arm/mach-stm32mp/cmd_stm32prog/stm32prog.c, in init_device(),
in case of RAW_IMAGE, part->size = block_dev->lba * block_dev->blksz.

  _ part->size is declared as u64.
  _ block_dev->lba is declared as lbaint_t which is uint64_t
    if CONFIG_SYS_64BIT_LBA is enable, otherwise ulong.
  _ block_dev->blksz is declared as unsigned long.

For example, in case block_dev->lba = 0x1dacc00, block_dev->blksz = 0x200
then part->size 0x5980000 which is incorrect as both are declared as ulong.

To fix this overflow issue, enable CONFIG_SYS_64BIT_LBA, block_dev->lba is
then declared as uint64_t and part->size get the correct value 0x3b5980000.
