ARM: dts: stm32: convert stm23f7 boards to OF_UPSTREAM
Enable OF_UPSTREAM flag for STM32F7 platforms.
Use upstream device tree for DSI and LTDC nodes,
As now in upstream DT, in panel@0 node, power-supply property is
present, which is a fixed-regulator, add DM_REGULATOR_FIXED flag
for stm32f769-disco boards.
Set also DEFAULT_FDT_FILE in defconfigs and use it in stm32f746-disco.h
to indicate which FDT file to load (All STM32F7 boards are using this
file).
If something is missing, it must be added in upstream device tree
in linux kernel ("px_clk" for DSI by example).
