[PATCH] drm: dw-hdmi: Fix compilation breakage by selecting REGMAP_MMIO

[Laurent Pinchart]

The dw-hdmi driver switched to regmap-mmio, but lacks the dependency in
Kconfig. This can result in compilation breakages. Fix it by selecting
REGMAP_MMIO.

Archit,

This is a v4.12 regression fix. While not super critical, it would be
nice if it could get merged in v4.12.
