Add bootph-all property in ltdc node to fix the following issue:

...
Video device 'display-controller at 48010000' cannot allocate frame buffer memory - ensure the device is set up before relocation
stm32_rifsc bus at 42080000: display-controller at 48010000 failed to bind on bus (-28)
stm32_rifsc bus at 42080000: Some child failed to bind (-28)
initcall_run_r(): initcall initr_dm() failed

Fixes: d0a838bdc629 ("Subtree merge tag 'v7.1-dts' of dts repo [1] into dts/upstream")
