[PATCH] USB: Handle over current inputs on all Intel controllers

This patch for the UHCI driver changes the test for over current inputs,
which can cause false Resume indications with some of Intel's USB
controllers.  Previously the code only checked for one specific controller
chip, but now another one has turned up that exhibits the same flaw.  It
seems best just to check for Intel being the manufacturer, especially
since it doesn't hurt to check for the condition when it isn't present or
is only temporary.
