drm/bridge: tc358768: fix THS_TRAILCNT computation
Correct computation of THS_TRAILCNT register.
This register must be set to a value that ensure that
THS_TRAIL > 60 ns + 4 x UI
and
THS_TRAIL > 8 x UI
and
THS_TRAIL < TEOT
with
TEOT = 105 ns + (12 x UI)
with the actual value of THS_TRAIL being
(1 + THS_TRAILCNT) x ByteClk cycle + ((1 to 2) + 2) xHSBYTECLK cycle +
- (PHY output delay)
with PHY output delay being about
(8 + (5 to 6)) x MIPIBitClk cycle in the BitClk conversion.
