[SCSI] mpt fusion: Add support for ATTO 4LD: Rebranded LSI 53C1030

Per request from Matthew Wilcox - using PCI_VENDOR_ATTO.

Add support for ATTO UL4D, they are rebranded 53C1030.
The changes are
1. Adding a new PCI vendor ID in pci table
2. The spi_port_page_2 is in different format than that of LSI generic
spi_port_page_2 and hence mapping code is added.
