drm: panel-simple: support TOPLAND TIAN G07017 LCD panel

The TIAN-G07017-01 is a 7" TFT-LCD module by TOPLAND ELECTRONICS (H.K).
The panel features 1024x600 24-bit RGB pixels driven over LVDS as well
as a PWM backlight and I2C-connected ft5506-compatible capacitive touch.

The panel description is taken from the Datasheet V0 (2024.5.23), but
it lists no timings and these were provided by the vendor separately.
