drm/bridge: tc358767: Fix use of unadjusted mode in the driver

Marek Vasut · robertfoss · commit b59d1d9d9ab2 · 2024-10-28T15:24:05.000+01:00
The driver configures mostly Pixel PLL from the clock cached in local copy of the mode. Make sure the driver uses adjusted mode which contains the updated Pixel PLL settings negotiated in tc_dpi_atomic_check()/tc_edp_atomic_check().
