disp: msm: sde: add support for hwfence profiling

Browse Source 
This change adds hwfence input and output fence profiling
registers and debugfs to enable them.
To enable input hw fences timestamps:
echo 0x1 > /d/dri/0/debug/hw_fence_status
To enable output hw fences timestamps:
echo 0x2 > /d/dri/0/debug/hw_fence_status
To enable both, input and output hw fences timestamps:
echo 0x3 > /d/dri/0/debug/hw_fence_status.
