drm/bridge: tc358768: fix THS_ZEROCNT computation
Correct computation of THS_ZEROCNT register.
This register must be set to a value that ensure that
THS_PREPARE + THS_ZERO > 145ns + 10*UI
with the actual value of (THS_PREPARE + THS_ZERO) being
((1 to 2) + 1 + (TCLK_ZEROCNT + 1) + (3 to 4)) x ByteClk cycle +
+ HSByteClk x (2 + (1 to 2)) + (PHY delay)
with PHY delay being about
(8 + (5 to 6)) x MIPIBitClk cycle in the BitClk conversion.
