Subject: [PATCH] drm/msm: fix PM_DEVFREQ kconfig dependency warning

Since DEVFREQ_GOV_SIMPLE_ONDEMAND depends on PM_DEVFREQ, the latter
should either be selected or DRM_MSM should depend on PM_DEVFREQ.
Since most drivers select PM_DEVFREQ instead of depending on it,
add a select here to satisfy kconfig.

WARNING: unmet direct dependencies detected for DEVFREQ_GOV_SIMPLE_ONDEMAND
  Depends on [n]: PM_DEVFREQ [=n]
  Selected by [y]:
  - DRM_MSM [=y] && HAS_IOMEM [=y] && DRM [=y] && (ARCH_QCOM || SOC_IMX5 || COMPILE_TEST [=y]) && COMMON_CLK [=y] && IOMMU_SUPPORT [=y] && (QCOM_OCMEM [=n] || QCOM_OCMEM [=n]=n) && (QCOM_LLCC [=n] || QCOM_LLCC [=n]=n) && (QCOM_COMMAND_DB [=y] || QCOM_COMMAND_DB [=y]=n)
