    raw/ntb: support AMD NTB
    
    Add support for the NTB endpoints integrated in AMD EPYC Embedded
    "Turin", "Genoa" and "Siena" processors to the raw/ntb driver.
    
    The AMD NTB uses a primary/secondary topology: one endpoint enumerates
    as the primary (device ID 0x14c0) and the other as the secondary
    (device ID 0x14c3). The hardware exposes two memory windows (BAR23 and
    BAR45), 16 doorbells and a single shared 16-register scratchpad bank.
    The scratchpad bank is split into two disjoint 8-register sets, one per
    side, so the driver uses a packed handshake layout that fits in 8
    registers, plugged in through the framework's dev_handshake,
    peer_mw_validate, read_peer_config and link_cleanup ops. Vendor-specific
    hardware (SMU) events are handled through the optional handle_hw_event
    op, and a memory-window alignment helper through the mem_align op.
    
    The AMD NTB uses an outbound translation window: a write to a BARxx
    memory window offset is forwarded to (xlat_base | offset) in the peer's
    memory rather than (xlat_base + offset). For that to be correct the
    translation base must be aligned to a power of two >= the window length
    so that no offset bit collides with a set bit in the base; the XLAT
    register also requires at least 4K alignment. The mem_align op reports
    this requirement through rte_pmd_ntb_get_mem_align(), and
    amd_ntb_mw_set_trans() rejects a misaligned base.
    
    On the secondary side the device's own PCIe link status does not
    reflect the true inter-host link, so the link speed and width are read
    from the upstream switch port via sysfs.
