please replace all lcdif related stuff since u-boot does support it
while Linux still not. To have consistency we should add this node to
Linux dts files too even if it's not supported. In the end .dts file is
a description of the hardware.

Same as lcdif, usbotg, ubsmisc and usbphy both supported in u-boot but
still not in Linux. So they must be kept and Linux dts must be updated.

I've given a fast review only on this patch since it's complex.
I'll give another check soon.
Have you tested this change too with the board?
Thank you!
Best regards
