Subject: [PATCH -next] drm/msm: DRM_DP_AUX_BUS depends on OF

Fix a Kconfig warning for DRM_MSM by making it depend on OF,
since 'select' does not follow any dependency chaings.

WARNING: unmet direct dependencies detected for DRM_DP_AUX_BUS
  Depends on [n]: HAS_IOMEM [=y] && DRM [=m] && OF [=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)

Fixes: f5d01644921b ("drm/msm: select DRM_DP_AUX_BUS for the AUX bus support")
