usbcore: refine warm reset logic
Current waiting time for warm(BH) reset in hub_port_warm_reset() is too short for xHC host to complete the warm reset and report a BH reset change. This patch increases the waiting time for warm reset and merges the function into hub_port_reset(), so it can handle both cold reset and warm reset, and factor out hub_port_finish_reset() to make the code looks cleaner. This fixes the issue that driver fails to clear BH reset change and port is "dead". Signed-off-by:Andiry Xu <andiry.xu@amd.com> Acked-by:
