cpufreq: airoha: modify CONFIG_OF dependency

Browse source 
Compile-testing without CONFIG_OF leads to a harmless build warning:

drivers/cpufreq/airoha-cpufreq.c:109:34: error: 'airoha_cpufreq_match_list' defined but not used [-Werror=unused-const-variable=]
  109 | static const struct of_device_id airoha_cpufreq_match_list[] __initconst = {
      |                                  ^~~~~~~~~~~~~~~~~~~~~~~~~

It would be possible to mark the variable as __maybe_unused to shut up
that warning, but a Kconfig dependency seems more appropriate as this still
allows build testing in allmodconfig and randconfig builds on all
architectures.

An earlier commit, b865a84046 ("cpufreq: airoha: Depends on OF"),
tried to fix it incorrectly. ARCH_AIROHA already requires CONFIG_OF, so
this change does nothing, and the dependency is still missing for the
COMPILE_TEST case.

Fix it properly.
