This serie aims to enable display support for the stm32mp135f-dk board

Those are only patches of the device-tree since the driver support has
already been added [1].

It respectivelly:
	- adds support for the display controller on stm32mp135
	- adds pinctrl for the display controller
	- enables panel, backlight and display controller on
	  stm32mp135f-dk

Finally it fixes the flags on the panel default mode in the
'panel-simple' driver, allowing to override the default mode by one
described in the device tree, and push further the blanking limit on the
panel.

Best regards,

I got the following errors during YAML verification:

Do I miss something ?
