ofnode: support panel-timings in ofnode_decode_display_timing
The "Display Timings" in panel-common.yaml can be provided by 2 properties
- panel-timing: when display panels are restricted to a single resolution
the "panel-timing" node expresses the required timings.
- display-timings: several resolutions with different timings are supported
with several timing subnode of "display-timings" node
This patch update the parsing function to handle this 2 possibility
when index = 0.
