[PATCH] drm/msm: fix new Konfig dependency warning

[Randy Dunlap]

DEVFREQ_GOV_SIMPLE_ONDEMAND depends on PM_DEVFREQ, so in order to
select the former safely, this symbol should also depend on
PM_DEVFREQ to avoid a Kconfig dependency warning.

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