npu2-opencapi: Add OpenCAPI OPAL API calls

Add three OPAL API calls that are required by the ocxl driver.

  - OPAL_NPU_SPA_SETUP

    The Shared Process Area (SPA) is a table containing one entry (a
    "Process Element") per memory context which can be accessed by the
    OpenCAPI device.

  - OPAL_NPU_SPA_CLEAR_CACHE

    The NPU keeps a cache of recently accessed memory contexts. When a
    Process Element is removed from the SPA, the cache for the link must be
    cleared.

  - OPAL_NPU_TL_SET

    The Transaction Layer specification defines several templates for
    messages to be exchanged on the link. During link setup, the host and
    device must negotiate what templates are supported on both sides and at
    what rates those messages can be sent.
