CMRR is a display feature that uses adaptive sync
framework to vary Vtotal slightly to match the
content rate exactly without frame drops. This
feature is a variation of VRR where it varies Vtotal
slightly (between additional 0 and 1 Vtotal scanlines)
to match content rate exactly without frame drops
using the adaptive sync framework.

enable this feature by programing new registers for
CMRR enable, CMRR_M, CMRR_N, vmin=vmax=flipline.The
CMRR_M/CMRR_N ratio represents the fractional part
in (actual refresh rate/target refresh rate) * origVTotal.

--v6:
- CMRR handling in co-existatnce of LRR and DRRS
- Correct vtotal paramas accuracy and add 2 digit precision.

--v7:
- Rebased patches in-accordance to AS SDP merge.
- Add neccessary gaurd to prevent crtc_state mismatch
during intel_vrr_get_config.

-v8:
- Add support for AS SDP for CMRR.
- update palce holder for CMRR register(Jani).
- Make CMRR as subset of FAVT, as per comments in patch#3.

-v9:
- Add CMRR register definitions to separate intel_vrr_reg.h.
- Remove cmrr_enabling/disabling, use vrr.enable instead.
- Update AS SDP pack function to accomodate target_rr_divider.
- Remove duplicated lines to compute vrr_vsync params.
- Set cmrr.enable with a separate patch at last.
