FIT image support is commonly used to bundle a kernel image, a device tree, and device tree overlays. Applying overlays requires the OF_LIBFDT_OVERLAY config option to be set, which lots of boards fail to select, most likely because developers never noticed. This leads to an error when trying to apply overlays:
"config with overlays but CONFIG_OF_LIBFDT_OVERLAY not set"
TI ARM boards select the option by default. Extend this to all systems that select the FIT option. This only affects the default, overlay support can still be disabled manually in the configuration.

I'm posting this as an RFC to get feedback. If the idea is generally appreciated, I'll update the defconfig files accordingly.
For i.MX, R-Car2/3, STM32MP1xx , this could be enabled just fine.
Enabling it for all fitImage systems sounds even better however, and the few which do not need DTO could disable this in board defconfig instead, I suspect there are fewer of those.
