[SCSI] megaraid_{mm,mbox}: 64-bit DMA capability checker
This patch contains - a fix for 64-bit DMA capability check in megaraid_{mm,mbox} driver. - includes changes (going back to 32-bit DMA mask if 64-bit DMA mask failes) suggested by James with previous patch. - addition of SATA 150-4/6 as commented by Vasily Averin. With patch, the driver access PCIconfiguration space with dedicated offset to read a signature. If the signature read, it means that the controller has capability to handle 64-bit DMA. Without this patch, the driver used to blindly claim 64-bit DMA capability. The issue has been reported by Vasily Averin [vvs@sw.ru]. Thank you Vasily for the reporting.
