[PATCH] drm/display: Fix HDMI state helper dependency

[Maxime Ripard <mripard@kernel.org>]

During the life of the series that introduced the
DRM_DISPLAY_HDMI_STATE_HELPER option, we reworked the Kconfig option
dependency setup to rely on depends on with commit f6d2dc03fa85 ("drm:
Switch DRM_DISPLAY_HDMI_HELPER to depends on") which got reverted later
on because it was creating too many issues by commit d7c128cb775e
("Revert "drm: Switch DRM_DISPLAY_HDMI_HELPER to depends on"").

However, since the series was out of tree at that time,
DRM_DISPLAY_HDMI_STATE_HELPER wasn't properly updated to take the revert
into account and is now creating build issues.

Let's switch the depends on to a select to fix this.
