msm: mdss: Add HFP_CALC_CLK way to switch frame rate

Browse source 
Add support to switch non-standard framerate.To achieve this,
first map the fps to standard fps and then tune pixel clock
based non-standard framerate. Panel porches might need update
before pixel clock tuning based on standard framerate mapping.
