fix(st): add max size for FIP in eMMC boot part

When putting FIP binary in eMMC boot partition (with STM32MP_EMMC_BOOT),
the FIP max size should be precised. If it is not, an assert fails in
io_block driver, as cur->size will be zero.
For this length, we then use the size of the eMMC boot partition minus
STM32MP_EMMC_BOOT_FIP_OFFSET.
