stm32f746g-disco/nxdemo also broken

We are waiting for LVGL 9.2.1 release lots of fixes incoming and if all works fine we will include it in NuttX 12.7.0 :-)

@cederom @xiaoxiang781216 This issue is not related to LVGL. fb and nxlines examples don't use LVGL, something else is broken.

This seems the same problem as reported by @TimJTi ?

Update: Nope, all problems that Tim had seems to be fixed already in the LVGL upstream :-)

@raiden00pl can you provide the output log of ‘fb’ ?

we want to check FB driver info first.
