xhci: move port specific items such as state completions to port structure

[ Upstream commit 2996e9fc ]

Now that we have a port structure for each port it makes sense to
move per port variables, timestamps and completions there.
Get rid of storing bitfileds and arrays of port specific items per bus.

Move
unsigned long           resume_done;
insigned long		rexit_ports
struct completion       rexit_done;
struct completion       u3exit_done;

Rename rexit_ports to rexit_active, and remove a redundant hcd
speed check while checking if rexit_active is set.
