mfd: Update abstract dbx500 interface
This prefixes a number of accessor functions with db8500_* since
they are DB8500-specific and we need to move to this naming
scheme.
We also replace numerous instances of machine_is() with cpu_is()
which covers the right type of ASICs rather than entire machines
i.e. boards.
