Subject: ASoC: codecs: rk3308: fix "defined but not used" warning on !OF
Building with CONFIG_OF=n triggers:
warning: 'rk3308_codec_of_match' defined but not used [-Wunused-const-variable=]
warning: unused variable 'rk3308_codec_of_match' [-Wunused-const-variable]
Even though OF is needed for probing, fix by declaring as __maybe_unused to
still allow building on non-OF configurations for build testing.
Fixes: 9fdd7b45da18 ("arm64: defconfig: enable Rockchip RK3308 internal audio codec driver")
Reported-by: kernel test robot <lkp@intel.com>
Closes: https://lore.kernel.org/oe-kbuild-all/202403271905.BYbGJiPi-lkp@intel.com/
