HDA has a use case for checking if a register is present in the cache
which it awkwardly open codes with use of _cache_only() and a read,
provide a direct API for this.

      regmap: Provide test for regcache_reg_present()
      ALSA: hda: Use regcache_reg_cached() rather than open coding

Sure, it's probably easiest (and there's some annoying overlap with some
other work in there that'd make for conflicts otherwise).
