MLK-16522-3 usb: cdns3: do not disable interrupt during role switch
After "MLK-16522-1 usb: cdns3: change cdns3_role_start work flow", the
software maintained role is current role which is doing role_start, so
it should handle its initialization routine well, just like we only has
one role and the interrupt is enabled at that time.
And disable interrupt causes one timeout problem during remove hcd, the
last command takes about 5 seconds to finish. See below for detail:

MLK-16522-2 usb: cdns3: host: change remove sequence for hcd
At probe, the main hcd is added first, then shared_hcd is added later,
so when we tries to remove hcds, the shared_hcd needs to remove first.

MLK-16522-1 usb: cdns3: change cdns3_role_start work flow
When it goes to start new role, the interrupt may be occurred before
role_start returns, but at this time, the cdns->role is still the old
role, so the interrupt handler will make mistake.
In this commit, we set desired role before role_start, if the role_start
has failed and the desired role is different with current one, it tries
to back current role.
