scsi: megaraid_sas: Add crash dump mode capability bit in MFI capabilities
In kdump kernel mode, the driver works in reduced functionality mode with
some features disabled such as reduced MSI-X count and RDPQ disabled, etc.
However, the firmware is not aware of this mode in some cases, which
results in undefined behavior.
To address this, the driver informs the firmware about the kdump mode
through MPI capabilities bit during driver initialization. This allows
firmware to adjust its behavior accordingly.
