IXP4xx: Prevent HSS transmitter lockup by disabling FRaMe signals.
With port configured with PCR_FRM_SYNC_OUTPUT* and external clock, bringing the hdlcX interface up and down without active clock supplied to the HSS causes a TX lockup. We don't support channelized/partial interfaces so FRaMe signals can't be used anyway, disabling them makes the lockup go away. Changes to this logic will be required if we want to support channelized HSS mode (this is most probably bug in NPE-A HSS firmware). Signed-off-by: Krzysztof Hałasa <khc@pm.waw.pl>
