sdm660-common: Refined early SF phase offsets

Browse source 
Sometimes SW_VSNC of DispSync comes 1ms earlier than signal_retire_fence(or HW_VSYNC)
It means VSYNC-sf only 5ms behind signal_retire_fence.
And VSYNC-sf will be 5.5ms earlier when applying early_sf_phase.
(the phase-sf changes from 6ms to 0.5ms)

Therefore, VSYNC-sf comes 0.5ms earlier than signal_retire_fence when
applying early_sf_phase for transaction and cause frame missed.

Add more 1ms to early_sf_phase then it will come 0.5 later than signal_retire_fence
in this case.

Bug: 118606025
Test: Open/close apps, observe no jank
Test: -Launch app, stay the same picture on screen at least 30s
      -Tap home key, observe no jank when doing app animation
