Neil Armstrong 3273fc63e1 drm/meson: Make DMT timings parameters and pixel clock generic 
Remove the modes timings tables for DMT modes and calculate the HW
paremeters from the modes timings.

Switch the DMT modes pixel clock calculation out of the static frequency
list to a generic calculation from a range of possible PLL dividers.

This patch is an intermediate step towards usage of the Common Clock
Framwework for PLL setup, by reworking the code to have common
sel_pll() function called by the CEA (HDMI) freq setup and the generic
DMT frequencies setup, we should be able to simply call clk_set_rate()
on the PLL clock handle in a near future.

The CEA (HDMI) and CVBS modes needs very specific clock paths that CCF will
never be able to determine by itself, so there is still some work to do for
a full handoff to CCF handling the clocks.

This setup permits setting non-CEA modes like :
- 1600x900-60Hz
- 1280x1024-75Hz
- 1280x1024-60Hz
- 1440x900-60Hz
- 1366x768-60Hz
- 1280x800-60Hz
- 1152x864-75Hz
- 1024x768-75Hz
- 1024x768-70Hz
- 1024x768-60Hz
- 832x624-75Hz
- 800x600-75Hz
- 800x600-72Hz
- 800x600-60Hz
- 640x480-75Hz
- 640x480-73Hz
- 640x480-67Hz

/**
* DOC: Video Encoder
*
* VENC Handle the pixels encoding to the output formats.
* We handle the following encodings :
*
* - CVBS Encoding via the ENCI encoder and VDAC digital to analog converter
* - TMDS/HDMI Encoding via ENCI_DIV and ENCP
* - Setup of more clock rates for HDMI modes
*
* What is missing :
*
* - LCD Panel encoding via ENCL
* - TV Panel encoding via ENCT
*
* VENC paths :
*
* .. code::
*
* _____ _____ ____________________
* vd1---| |-| | | VENC /---------|----VDAC
* vd2---| VIU |-| VPP |-|-----ENCI/-ENCI_DVI-|-|
* osd1--| |-| | | \ | X--HDMI-TX
* osd2--|_____|-|_____| | |\-ENCP--ENCP_DVI-|-|
* | | |
* | \--ENCL-----------|----LVDS
* |____________________|
*
* The ENCI is designed for PAl or NTSC encoding and can go through the VDAC
* directly for CVBS encoding or through the ENCI_DVI encoder for HDMI.
* The ENCP is designed for Progressive encoding but can also generate
* 1080i interlaced pixels, and was initialy desined to encode pixels for
* VDAC to output RGB ou YUV analog outputs.
* It's output is only used through the ENCP_DVI encoder for HDMI.
* The ENCL LVDS encoder is not implemented.
*
* The ENCI and ENCP encoders needs specially defined parameters for each
* supported mode and thus cannot be determined from standard video timings.
*
* The ENCI end ENCP DVI encoders are more generic and can generate any timings
* from the pixel data generated by ENCI or ENCP, so can use the standard video
* timings are source for HW parameters.
