Similar to the previous commit, convert drivers open coding OF graph
parsing to use drm_of_find_panel_or_bridge instead.
This changes some error messages to debug messages (in the graph core).
Graph connections are often "no connects" depending on the particular
board, so we want to avoid spurious messages. Plus the kernel is not a
DT validator.

This patch fixed the bellow no DRM_INFO is printed issue:
if (!delay_count)
DRM_INFO("phylock and phystopstateclklane is not ready.\n");
There will some printed issues with above info, under certain
circumstances:
If ((BIT(0) | BIT(2)) & val) is never true, break will not happen and
delay_count will be max u32 value (?), and no DRM_INFO is printed.
Also if ((BIT(0) | BIT(2)) & val) is true at the last possible
loop round, break happens, but now delay_count is already zero
( because of earlier delay_count-- ) and DRM_INFO is erroneously
printed.
Thanks to Juha Leppänen, he reports to me this issue.
