disp: msm: sde: add support for INTF line/frame count reset

Browse Source 
From MDSS 8.x INTF line/frame counters can be reset through
a register. Reset these counters during timing engine enable /
tear-check enable to keep track of meaningful counters, which
would be useful during debugging. Additionally, reset the
counters during cont-splash modeset to track the number of
auto-refresh frames while disabling it during the first frame.
