drm/msm/dp: Add capability to parser and retrieve max DP link supported rate from link-frequencies property of dp_out endpoint
Changes in v6:
-- second patch after split parser patch into two patches
Changes in v7:
-- without checking cnt against DP_MAX_NUM_DP_LANES to retrieve link rate
Changes in v9:
-- separate parser link-frequencies out of data-lanes
Changes in v10:
-- add dp_parser_link_frequencies()
Changes in v11:
-- return 0 if(!endpoint)
Changes in v12:
-- replace khz with kbytes at dp_parser.h
Changes in v14:
-- replace "parser" with "parse" at commit subject
-- use do_div() for 64 bits division
