The below patches add support for data flow metering as mentioned in the section 6.5.6 FRL data flow metering of HDMI 2.1 specification. Add functions to calclulate the DFM parameters for the given frl config, which is further used to evaluate the data flow metering requirement as specified in the spec. As per the spec the below patches implement the frl capacity computation functions for both compressed and uncompressed video. Finally exposing 1 function each for compressed and uncompressed video to figure out if the data flow metering requirement is met or not. v2: Changed u32 to unsigned int, corrected patch 4 to address build issue, addressed checkpatch issues, moved the drm_frl_dfm_helper under kms_helpers section for compilation in the Makefile.
