Rename the file bcm283x-uboot.dtsi so that it get
automatically include through the scripts/Makefile.lib
using $(CONFIG_SYS_SOC))-u-boot.dtsi
Without this uarts and pincontroller miss the property dm-pre-reloc
and the first call to bcm283x_mu_serial_ofdata_to_platdata() fails
as the pins are not set correctly.
As a result the U-Boot banner isn't shown on boot.
Before commmit
143256b353 ("fdt: update bcm283x device tree sources to Linux 5.1-rc6 state")
we included bcm283x-uboot.dtsi directly in the device-tree file.
Which got deleted by the metioned commit.
This is a much robuster solution.

In commmit
143256b353 ("fdt: update bcm283x device tree sources to Linux 5.1-rc6 state")
we deleted the label for the node soc from bcm283x.dtsi
As we don't need to add the property dm-pre-reloc to the soc node,
we can delete it from bcm283x-uboot.dtsi

When U-Boot started using SPDX tags we were among the early adopters and
there weren't a lot of other examples to borrow from. So we picked the
area of the file that usually had a full license text and replaced it
with an appropriate SPDX-License-Identifier: entry. Since then, the
Linux Kernel has adopted SPDX tags and they place it as the very first
line in a file (except where shebangs are used, then it's second line)
and with slightly different comment styles than us.
In part due to community overlap, in part due to better tag visibility
and in part for other minor reasons, switch over to that style.
This commit changes all instances where we have a single declared
license in the tag as both the before and after are identical in tag
contents. There's also a few places where I found we did not have a tag
and have introduced one.

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.

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.
