pau: update current opal call functions

Update the content of three current OPAL API calls to support PAU.

  - 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 PAU 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.
