thunderbolt: Verify Router Ready bit is set after router enumeration

Browse source

The USB4 Connection Manager guide specifies that after enumerating a
router, the Connection Manager shall verify that the Router Ready bit
(ROUTER_CS_6.RR) has been set to ensure hardware configuration has completed.
Currently, this step is missing from the enumeration sequence.

Add this check to follow the Connection Manager guide more closely.
