Revert "drm: Make drivers depends on DRM_DW_HDMI"

This reverts commit c0e0f139354c01e0213204e4a96e7076e5a3e396, as helper
code should always be selected by the driver that needs it, for the
convenience of the final user configuring a kernel.

The user who configures a kernel should not need to know which helpers
are needed for the driver he is interested in. Making a driver depend
on helper code means that the user needs to know which helpers to enable
first, which is very user-unfriendly.
