HDMI standard defines recommended N and CTS values for Audio Clock Regeneration. Currently each driver implements those, frequently in somewhat unique way. Provide a generic helper for getting those values to be used by the HDMI drivers. The helper is added to drm_hdmi_helper.c rather than drm_hdmi_audio.c since HDMI drivers can be using this helper function even without switching to DRM HDMI Audio helpers. Note: currently this only handles the values per HDMI 1.4b Section 7.2 and HDMI 2.0 Section 9.2.1. Later the table can be expanded to accommodate for Deep Color TMDS char rates per HDMI 1.4 Appendix D and/or HDMI 2.0 / 2.1 Appendix C).
