Add register definitions for Transcoder Fixed Average Vtotal mode/CMRR function, with the necessary bitfields. Compute these registers when CMRR is enabled, extending Adaptive refresh rate capabilities. --v2: - Use intel_de_read64_2x32 in intel_vrr_get_config. [Jani] - Fix indent and order based on register offset. [Jani] --v3: - Removing RFC tag. --v4: - Update place holder for CMRR register definition. (Jani) --v5: - Add CMRR register definitions to a separate file intel_vrr_reg.h. --v6: - Fixed indentation. (Jani) - Add dependency header intel_display_reg_defs.h.
