ARM: sa1111: provide a generic way to prevent devices from registering

Browse Source 
Some platforms don't want certain devices to be registered, because,
eg, the interface is not wired.  Provide a way for platforms to
prevent various devices from being registered via a devid bitmask in
the platform data.
