[PATCH] [v1] coresight: funnel: inport schedule by priority can not take work

[Chao Xu]

Before enable funnel, priority must be set. Changing the port
priorities in real time is not supported. If the priority control
register is written when one or more of ports are enable, then
the write is silently rejected.
