Log Message:
Use device_t and its accessors throughout.  Use aprint_*_dev().

Improve PMF-ability.

        Add a 'flags' argument to suspend/resume handlers and
        callers such as pmf_system_suspend().

        Define a flag, PMF_F_SELF, which indicates to PMF that a
        device is suspending/resuming itself.  Add helper routines,
        pmf_device_suspend_self(dev) and pmf_device_resume_self(dev),
        that call pmf_device_suspend(dev, PMF_F_SELF) and
        pmf_device_resume(dev, PMF_F_SELF), respectively.  Use
        PMF_F_SELF to suspend/resume self in ath(4), audio(4),
        rtw(4), and sip(4).

        In ath(4) and in rtw(4), replace the icky sc_enable/sc_disable
        callbacks, provided by the bus front-end, with
        self-suspension/resumption.  Also, clean up the bus
        front-ends.  Make sure that the interrupt handler is
        disestablished during suspension.  Get rid of driver-private
        flags (e.g., RTW_F_ENABLED, ath_softc->sc_invalid); use
        device_is_active()/device_has_power() calls, instead.

        In the network-class suspend handler, call if_stop(, 0)
        instead of if_stop(, 1), because the latter is superfluous
        (bus- and driver-suspension hooks will 'disable' the NIC),
        and it may cause recursion.

        In the network-class resume handler, prevent infinite
        recursion through if_init() by getting out early if we are
        self-suspending (PMF_F_SELF).

rtw(4) improvements:

        Destroy rtw(4) callouts when we detach it.  Make rtw at
        pci detachable.  Print some more information with the "rx
        frame too long" warning.

Remove activate() methods:

        Get rid of rtw_activate() and ath_activate().  The device
        activate() methods are not good for much these days.

Make ath at cardbus resume with crypto functions intact:

        Introduce a boolean device property, "pmf-powerdown".  If
        pmf-powerdown is present and false, it indicates that a
        bus back-end should not remove power from a device.

        Honor this property in cardbus_child_suspend().

        Set this property to 'false' in ath_attach(), since removing
        power from an ath at cardbus seems to lobotomize the WPA
        crypto engine.  XXX Should the pmf-powerdown property
        propagate toward the root of the device tree?

Miscellaneous ath(4) changes:

        Warn if ath(4) tries to write crypto keys to suspended
        hardware.

        Reduce differences between FreeBSD and NetBSD in ath(4)
        multicast filter setup.

        Make ath_printrxbuf() print an rx descriptor's status &
        key index, to help debug crypto errors.

        Shorten a staircase in ath_ioctl().  Don't check for
        ieee80211_ioctl() return code ERESTART, it never happens.
