YueHaibing 876271118a drm/display: Fix build error without CONFIG_OF 
While CONFIG_OF is n but COMPILE_TEST is y, we got this:

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

Make DRM_DP_AUX_BUS depends on OF || COMPILE_TEST to fix this warning.
