fdt: adjust bcm283x device tree for u-boot The information currently set via platdata has to be represented in the device tree now. bcm283x-uboot.dtsi adds the u-boot specific "skip-init" property to the serial nodes and enables initialization in the pre-reloc phase.

bcm2835_pinctrl: Probe pre-reloc The serial drivers now depend on the pinctrl driver to determine whether they are enabled. That means if a serial device wants to be used pre-reloc, we also need the pinctrl device pre-reloc. Adapt the pinctrl driver as well as dts overlay accordingly.
