drm/msm/sde: add debugfs nodes for underruns debug
This change adds debugfs nodes for debugging underruns,
after this change following commands are supported:
1. To enable the underrun ftrace:
echo 1 > /d/tracing/events/sde/sde_encoder_underrun/enable
2. To enable feature that disables the ftraces once the
underrun happens:
echo 1 > /d/dri/0/debug/dbg_ctrl
3. To enable the panic in the device when underrun happens:
