mfd: arizona: Allow building arizona MFD-core as module
There is no reason why the arizona core,irq and codec model specific regmap bits cannot be build as a module. All they do is export symbols which are used by the arizona-spi/i2c and arizona-codec modules, which themselves can be built as module. Change the Kconfig and Makefile arizona bits so that the arizona MFD-core can be built as a module. This is especially useful on x86 platforms with a WM5102 codec, this allows the arizona MFD driver necessary for the WM5102 codec to be enabled in generic distro-kernels without growing the base kernel-image size. Note this also adds an explicit "depends on MFD_ARIZONA" to all the arizona codec Kconfig options. The codec drivers use functions from mfd arizona-core. These new depends are necessary to disallow the codec drivers being builtin when the arizona-core is build as a module, otherwise we end up with missing symbol errors when building vmlinuz.
