[PATCH] : Allow embedded developers USB options normally reserved for OTG

[Robin Getz <rgetz@xxxxxxxxxxxxxxxxxxxx>]

From: Robin Getz <rgetz@xxxxxxxxxxxxxxxxxxxx>

Allow embedded developers to turn support for USB Hubs off even if they have a 
full root hub. This saves the overhead (RAM and Flash size).

Allow embedded developers the capabilities of the "otg_whitelist.h" - a 
product whitelist, so USB peripherals not listed there will be rejected 
during enumeration. This is the desired operation for many embedded products.
