[SCSI] aacraid: expose physical devices for models with newer firmware 



The default driver setting is "expose_physicals=0", which means raw
physical drives are not exposed to OS.  If the user wants to expose
connected physical drives, enable "expose_physicals" module parameter.
With the new JBOD firmware, physical drives are not available for
"expose_physicals>0".  In function "aac_expose_phy_device", modified
to reset the appropriate bit in the first byte of inquiry data.  This
fix exposes the connected physical drives.
