[PATCH] [SCSI] mpt fusion: Fix 32 bit platforms with 64 bit resources.

[Pravin Bathija]

    Powerpc 44x uses 36 bit real address while the real address defined
    in MPT Fusion driver is of type 32 bit. This causes ioremap to fail and driver
    fails to initialize. This fix changes the data types representing the real
    address from unsigned long 32-bit types to resource_size_t which is 64-bit. The
    driver has been tested, the disks get discovered correctly and can do IO.
