rockchip: video: introduce VIDEO_DW_HDMI and select for Rockchip HDMI

Browse Source 
Instead of having drivers/video/rockchip/Kconfig point outside of its
hierarchy for dw_hdmi.o, we should use a configuration-option to
include the Designware HDMI support.

This change introduces a new config option (not to be selected via
menuconfig, but to be selected from a dependent video driver's
configuration option) that enables dw_hdmi.o and selects it whenever
the HDMI support for Rockchip SoCs is selected.

Enables the common driver code for the Designware HDMI TX
block found in SoCs from various vendors.
As this does not provide any functionality by itself (but
rather requires a SoC-specific glue driver to call it), it
can not be enabled from the configuration menu.
