Subject: [PATCH] [RFC] [SCSI] mpt fusion: add support for 0x1000/0x0055

The device identifies itself as

0d:05.0 SCSI storage controller: LSI Logic / Symbios Logic SAS1068 PCI-X Fusion-MPT SAS (rev 01) Subsystem: NEC Corporation SAS1068

and seems to be functionally compatible with 0x0054 PID.

The request for support of this device has been raised on mailinglists several
times in the past (see [1] [2] and more), but aparently the PCI ID never made it
to mptsas_pci_table[].

I guess the "Subsystem: NEC Corporation" is telling us some rebranding 
story, including the PID change ... ?
