ARM: dts: r8a7793: gose: Add HDMI video out support
This patch adds r8a7793 GOSE HDMI video out support. The r8a7793 GOSE board is similar to r8a7791 Koelsch. For those boards an on-board HDMI encoder chip provides HDMI video out and also a LVDS port is available for external LCD panels. Tested on r8a7793 Gose with HDMI hooked up to a Toshiba TV.
