drm/komeda: Add engine clock requirement check for the downscaling
For downscaling there is a restriction, the downscaling needed engine
clock can not acceed the real engine clock, and the clock requirement
mostly depend on the specific HW, to solve this problem:
1. Add a pipeline func - downscaling_clk_check for CORE to query the real
HW if downscaling can be supported.
2. Add new property clock ratio which is the ratio of:
(mclk << 32) / pxlclk
then User driver can use this ratio to do the clock check to avoid post
an invalid downscaling to kernel.
v2: Rebase and Delete debug print
