driver/spi: Warn when probed SF size differs from CONFIG_ROM_SIZE

Some assumptions are made with respect to CONFIG_ROM_SIZE being the
actual size of the boot medium, e.g. when automatically creating an
fmap with and RW_MRC_CACHE region. It is therefore a good to warn the
user when this is not the case.
