[PATCH] Add helper for registering a fixed regulator

[Sascha Hauer]

Hi,

The following adds a helper for registering a fixed dummy regulator
making it simple for boards which have no software controllable regulator
for certain devices to register a fixed regulator as a dummy.

The last two patches make smsc911x ethernet functional again which
broke when the smsc911x driver gained regulator support.
