drm/panel: simple: Convert Innolux G121X1-L03 to display_timing

Use display_timing instead of drm_display_mode to define a range of
possible display timings supported by this panel. This makes the panel
support more flexible and improves compatibility. No functional change
is expected.

The settings are picked from documentation [1] section 6.1 INPUT SIGNAL
TIMING SPECIFICATIONS.
