x86: fsp: Show FSP-S or FSP-M address in fsp_get_header()

Browse source 
At present this function only supports FSP-M but it is also used to read
FSP-S, in which case FSP-M may be zero. Add support for showing whichever
address is present in the FSP binary.

Also change the debug() statements to log_debug() while here.
