[PATCH 5/5] drm/panel: st7703: Drive XBD599 panel at higher clock rate

[Frank Oltmanns]

This panel is used in the pinephone that runs on a Allwinner A64 SOC.
Acoording to it's datasheet, the SOC requires PLL-MIPI to run at more
than 500 MHz.

Therefore, change [hv]sync_(start|end) so that we reach a clock rate
that is high enough to drive PLL-MIPI within its limits.
