isci: fix 32-bit operation when CONFIG_HIGHMEM64G=n commit ee33e2b771f9e9e4aaba2bb2ace7b727fe451a8b upstream. The unsolicited frame control infrastructure requires a table of dma addresses for the hardware to lookup the frame buffer location by an index. The hardware expects the elements of this table to be 64-bit quantities, so we cannot reference these elements as dma_addr_t. All unsolicited frame protocols are affected, particularly SATA-PIO and SMP which prevented direct-attached SATA drives and expander-attached drives to not be discovered.
