msm: mdss: reduce mdp bandwidth for single pipe use case

For single layer use case, mdp prefill bandwidth request can be
reduced because mdp pipe operates like a fifo and there is no need to
fill all buffers before the active region.

msm: mdss: add bandwidth check per pipe

Add check to verify that the bandwidth of a pipe does not exceed
the threshold per pipe. The check happens during the overlay setup
and if the pipe exceed the limit, the driver will try to decimate to
reduce the bandwidth; but even if after decimation the limit is
exceeded, it will fail the configuration.

msm: mdss: remove additional vert decimation when per pipe BW exceeds

Currently if per pipe BW exceeds pre-defined limit, we add additional
vertical decimation to reduce BW. But this has inverse effect on quality.
To mitigate this issue, decimate further only if user has already
requested decimation else return an appropriate error which user can
detect and act upon it.

msm: mdss: Tune watermark and prefill BW based on minimum SMP bytes

Modify watermark levels and prefill BW calculation
to be set based on the minimum prefill buffer bytes from
the SMP. Add debugfs property to dynamically tune the minimum
bytes for debugging
