fsp_broadwell_de: Refactor code for SPI debug messages

Currently boards based on fsp_broadwell_de fail to compile if the config
    switch CONFIG_DEBUG_SPI_FLASH is selected. The error is caused by the
    usage of const for the address pointer in the functions writeb_, writew_
    and writel_. The reason why it stayed hidden for so long is the fact that
    the switch is used with the preprocessor and nobody really selects it
    until there is a bug one want to find in this area.

This patch fixes the parameter type definition which solves the error.
    In addition the config switch is not used on preprocessor level anymore
    but instead on compiler level. This ensures that at least the code
    syntax is checked on build time even if the config option is not
    selected. Also prefix the messages with "SPI:" to make them more
    meaningful in a full log.
