drm/bridge: tc358768: fix TCLK_ZEROCNT computation
Correct computation of TCLK_ZEROCNT register.
This register must be set to a value that ensure that
(TCLK-PREPARECNT + TCLK-ZERO) > 300ns
with the actual value of (TCLK-PREPARECNT + TCLK-ZERO) being
(1 to 2) + (TCLK_ZEROCNT + 1)) x HSByteClkCycle + (PHY output delay)
with PHY output delay being about
(2 to 3) x MIPIBitClk cycle in the BitClk conversion.
Fixes: ff1ca6397b1d ("drm/bridge: Add tc358768 driver")
