disp: msm: sde: add support for ppb size programming

MDSS 10.0 onwards, hw supports programming of pingpong
latency buffer size based on the resolution of display.
In prior targets full size of the latency buffer is used.
This change adds required support in sde driver to program
the pingpong buffer size based on systems recommended
latency lines requirement and the display resolution.
