Linus Walleij 94be70d4b2 mfd: Break out ab5500 debugfs code
This breaks the debugfs portions of the AB5500 driver into its own
file. Split off a _raw function to access registers since we don't
want to expose a generically named function globally. Move all
required data structures to a shared ab5500-core.h file.
