drm/ingenic: Add dw-hdmi driver specialization for jz4780
A specialisation of the generic Synopsys HDMI driver is employed for
JZ4780 HDMI support. This requires a new driver, plus device tree and
configuration modifications.
Here we add Kconfig DRM_INGENIC_DW_HDMI, Makefile and driver code.
Note that there is no hpd-gpio installed on the CI20 board HDMI
connector. Hence there is no hpd detection by the connector driver
and we have to enable polling in the dw-hdmi core driver.
For that we need to set .poll_enabled but that struct component
can only be accessed by core code. Hence we use the public
setter function drm_kms_helper_hotplug_event() introduced before.
Also note that we disable Color Space Conversion since it is not
working on jz4780.
