With the upcoming consolidation of normal MUXs and virtual MUXs we need to be able to distinguish between enums with and without a backing register at the enum level. Use the same approach as used for virtual mixer controls by setting the reg field of the enum to SND_SOC_NOPM for enums without a backing register. This patch adds a set of helper macros that can be used to define such enums.

Could you replace "max" with "items"?
