[PATCH] prism54usb: Fix hail of warnings on 64bit platforms

[Alan Cox]

If you want to cast a pointer to a small value then start by turning it
into an unsigned long so the compiler knows what is going on.

Personally I find the whole approach used by this driver for types of
registers (which are really USB register numbers) utterly perverse...
