[SCSI] stex: add new device (id 0x8650) support
A new device (id 0x8650, nickname 'yosemite') support is added. It's basically the same, except for following items: - mapping of id and lun by firmware - special handling for some commands in interrupt routine - change of internal copy function for these special commands - different reset handling code - different shutdown notification command Signed-off-by: Ed Lin <ed.lin@promise.com> Signed-off-by: James Bottomley <James.Bottomley@SteelEye.com>
