[PATCH 11/13] ARM: dts: stm32: fix LTDC port node on STM32 MCU ad MPU

[Alexandre Torgue]

Running "make dtbs_check W=1", some warnings are reported concerning
LTDC port subnode:

/soc/display-controller at 5a001000/port:
unnecessary #address-cells/#size-cells without "ranges" or child "reg"
property
/soc/display-controller at 5a001000/port: graph node has single child node
'endpoint', #address-cells/#size-cells are not necessary
