[PATCH v2 -next] soc: mediatek: Fix Kconfig warning

[YueHaibing]

WARNING: unmet direct dependencies detected for MTK_MMSYS
  Depends on [n]: (ARCH_MEDIATEK [=y] || COMPILE_TEST [=n]) && COMMON_CLK_MT8173_MMSYS [=n]
  Selected by [y]:
  - DRM_MEDIATEK [=y] && HAS_IOMEM [=y] && DRM [=y] && (ARCH_MEDIATEK [=y] || ARM && COMPILE_TEST [=n]) && COMMON_CLK [=y] && HAVE_ARM_SMCCC [=y] && OF [=y]

Make MTK_MMSYS select COMMON_CLK_MT8173_MMSYS to fix this.
