Linus Walleij df1e0520f9 ARM: 5666/1: Revamped U300 padmux API
This abstracts the hackish padmux API on the U300 platform into
something more manageable. It provides a way for drivers to
activate/deactivate a certain padmux setting. It will also switch
the users of the old API over to using the new style, pushing
muxing into the apropriate setup files.
