[SCSI] mpt fusion: logging support in Kconfig, Makefile, mptbase.h and addition of mptdebug.h
This patch adds a new file mptdebug.h in the fusion source directory,
which contains different debug macros. The existing debug macros and
flags are removed from the mptbase.h and Makefile In Kconfig a new
configuration parameter FUSION_LOGGING is added to enable/disable the
logging support during compile time.
