USB: fix up EHCI startup synchronization
patch 1cb52658b4f5b10a9e91f8e1c21ca2bcc1b9a3ca in mainline.
A recent patch added software synchronization during EHCI startup,
so ports aren't switched away from the companion controllers after
resets have started. This patch adds a short delay letting hardware
finish that port switching before any new resets begin ... so both
ends of that hardware race window are closed.
