Subject: [PATCH] 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".
