Bug Description
===SRU Justification===
[Impact]
Currently we need to recompile the entire kernel if we want try quirks
in usbcore.
[Test]
Use kernel parameter "usbcore.quirks=" in conjunction with dynamic debug
for usbcore, we can see that usb quirks successfully enabled for USB
devices dynamically.
[Fix]
Introduce a new module parameter, "usbcore.quirks=". Users now can try
different quirks without compiling anything.
[Regression Potential]
Low. It doesn't change any behavior of usb driver per se, it simply adds
new logic to detect quirks.
