Subject: [PATCH] usb: xhci: add support for performing fake doorbell

Broadcom's Northstar XHCI controllers seem to need a special start
procedure to work correctly. There isn't any official documentation of
this, the problem is that controller doesn't detect any connected
devices with default setup. Moreover connecting USB device to controller
that doesn't run properly can cause SoC's watchdog issues.

A workaround that was successfully tested on multiple devices is to
perform a fake doorbell. This patch adds code for doing this and enables
it on BCM4708 family.
