    IB/ipath: Generalize some xxx_SHIFT macros
    
    In preparation for upcoming chips that have different values for
    INFINIPATH_R_PORTENABLE_SHIFT, INFINIPATH_R_INTRAVAIL_SHIFT,
    INFINIPATH_R_TAILUPD_SHIFT, and portcfg_shift, remove the shared
    #defines and use device-specific variables instead.
