[PATCH v3] ASoC: sunxi: do not select COMMON_CLK to fix builds

[Krzysztof Kozlowski]

COMMON_CLK is a user-selectable option with its own dependencies.  The
most important dependency is !HAVE_LEGACY_CLK.  User-selectable drivers
should not select COMMON_CLK because they will create a dependency cycle
and build failures.  For example on MIPS a configuration with COMMON_CLK
(selected by SND_SUN8I_CODEC) and HAVE_LEGACY_CLK (selected by
SOC_RT305X) is possible:

  WARNING: unmet direct dependencies detected for COMMON_CLK
    Depends on [n]: !HAVE_LEGACY_CLK [=y]
    Selected by [y]:
    - SND_SUN8I_CODEC [=y] && SOUND [=y] && !UML && SND [=y] && SND_SOC [=y] &&
      (ARCH_SUNXI || COMPILE_TEST [=y]) && OF [=y] && (MACH_SUN8I || ARM64 && ARCH_SUNXI || COMPILE_TEST [=y])
