Here it makes a little advantage over more uglified code.

I'm not sure it makes sense. Those fields are filed according to ACPI
specification and applies to the platform in question. Usually you don't
need to look into them on regular basis, perhaps one time per each
platform which uses such combination of SoC + ASoC + Codec which is
quite unlikely to be more than once twice per year(?).

So, for over few dozens of drivers which are using GPIO ACPI mapping
tables this is the first request like this I see.

Thus, if you insist, I can do it, but my vote is "it doesn't worth of
doing it at all".
