docs(st): one device flag for ST platforms

Due to embedded SRAM used to load BL2 and BL31 or BL32 has a limited
size, only one storage device or serial device flag should be selected
in TF-A build command line for ST platforms.
This is in line with STMicroelectionics recommendation [1] about those
compilation flags.
