scsi: megaraid_sas: fw_reset_no_pci_access required for MFI adapters only
fw_reset_no_pci_access is only applicable for MFI controllers and is not
used for Fusion controllers.
For all Fusion controllers, driver can check reset adapter bit in
status register before performing a chip reset without
setting "fw_reset_no_pci_access".
