[SCSI] mptfusion: Added sysfs expander manufacture information at the time of expander add.
Added new function mptsas_exp_manufacture_info, which will obtain the REPORT_MANUFACTURING, and fill the details into the sas_expander_device object when the expander port is created. Signed-off-by: Kashyap Desai <kashyap.desai@lsi.com> Signed-off-by: James Bottomley <James.Bottomley@suse.de>
