No display output device could be found after the monitor is plugged into the hub. [Fix] Intel provide a new patch to fix this issue on ADL platforms. [Test] Verified on ADL platform with different type-c hubs, the display output works. [Where problems could occur] The TCSS_DDI_STATUS register is indexed by tc_port not by the FIA port index. So, this patch is more like a fix and only affect ADL platforms. And as the commit log describes, the value is wrong on TC#3/4 ports, so it won't affect the origin working ports.
