Add support for a boot argument podule?=mmmmpppp to enable the manufacturer 

and product IDs for a podule to be overriden. The IDs are specified in hex.
A value of "ffff" means disable and replaces the podule?.disable option.
This allows podules whose IDs have been changed e.g. by PowerROMs to still
have the correct driver attached.
Based on my original patch but tided up and debugged by Stephen Hobbs.
