Add -u-boot.dtsi files to keep the current U-Boot behaviour:
- add u-boot,dm-pre-reloc where required
- disable watchdog
- set uart clock frequency
- add gpio bank-name properties
where appropriate:
- make qspi work (add alias for spi0, fix compatible for flash)
- enable usb (status okay, add alias for udc0)
Adapt board dts files that are not in Linux to keep their old
behaviour.
Change licenses to SPDX.
(Patman warnings/errors are in 1:1 copied files from Linux)

Device trees need to have the serial console device available
before relocation and require a stdout-path in chosen at least
for SPL to have a console.

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.

This patch adds "spi-flash" to the compatible list of the qspi flash
chip for all socfpga boards. This is required to make qspi work on
these boards on top of the recent fixes. Without the "spi-flash"
compatible string for the flash chip, the speed cannot be read and a
speed of 0Hz is used (which results in a divide-by-zero on these
boards).

This patch adds the necessary OF alias for the UDC node, which let's
the code locate the DWC2 UDC base address in OF instead of hard-coding
it into the U-Boot binary. The code is adjusted to use the address from
OF instead of the hard-coded one. Finally, the hard-coded address is
removed and USB DM support is enabled.

The SPI aliases are completely wrong. First, they point to non-existing
/spi@.* nodes instead of the correct /soc/spi@.* nodes. Second, the use
ad-hoc string instead of a handle. Furthermore, they are copied multiple
times in each board DTS.
So fix it such that we move these into socfpga.dtsi and make them use
the usual handles.
