drivers/mipi: Fix pixel clock and enable C-PHY for TM_TL121BVMS07_00C

Browse source 
Commit ddf5987c1e ("drivers/mipi: Add support for
TM_TL121BVMS07_00C panel") (CB:89216) added support for the
TM_TL121BVMS07_00C panel, but the screen was not functional.

Decrease the pixel clock from 4,400,560 Hz to 264,355 Hz to match the
actual panel timing specification. Also, the panel uses C-PHY interface,
so enable the `PANEL_FLAG_CPHY` flag accordingly.
