[RFC v2 0/5] Add data flow metering support for HDMI2.1

[Vandita Kulkarni]

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.
