[SCSI] aic94xx: tie driver to the major number of the sequencer firmware

Browse source 
The sequencer firmware file has both a string (currently showing
V17/10c6) and a number (currently set to 1.1).  It has become apparent
that Adaptec may issue sequencer firmware in the future which could be
incompatible with the current driver.  Therefore, the driver will be
tied to the particular major number of the firmware (i.e. the current
driver will load any 1.x firmware).  Additionally, the driver will print
out both the ascii string and the major number, so with this pach the
current firmware will print out

aic94xx: Found sequencer firmware version 1.1 (V17/10c6)
