rockchip: video: introduce VIDEO_DW_HDMI and select for Rockchip HDMI
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.
