    mpi3mr: Add bare-bones manual
    
    The mpi3mr driver is written by Broadcom for the 9600 Series 24G PCIe
    4.0 Tri-Mode RAID Adapters and eHBAs boards. This is 3rd-Generation
    Tri-Mode x8 and x16 NVMe/SAS/SATA (although Broadcom/Avago did muddy the
    waters by having multiple 2nd generations cards and referring to them
    inconsistently).
