mfd: arizona: Remove use of codec build config #ifdefs
Remove the use of #ifdefs around each case statement of the chip ID and type validation switches. We must ensure that the contained code still compiles to nothing if support for that codec was not built into the kernel, to prevent creation of link references to missing functions. So the ifdefs are replaced with a use of the IS_ENABLED() macro.
