Previously, the TX LED would flash but nothing would appear on the
serial port, and the board would appear dead with a build of the
socfpga_cyclone5_defconfig. I have verified that adding the frequency to
the uart will fix the serial console on my board.

The SPL for socfpga gen5 currently takes all peripherals out of reset
unconditionally. To implement proper reset handling for peripherals,
the reset node has to be provided with the SPL dts.
In preparation to move the DDR driver to DM, the sdr node is required
in SPL, too.
This patch adds "u-boot,dm-pre-reloc" to U-Boot specific dtsi addon
files so that the reset manager and SDR driver correctly probe in SPL.
It centralizes these settings into a common file since in contrast to
boot-type specific nodes, "soc", "rst" and "sdr" are always needed.

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.

Add CycloneV based Terasic DE1-SoC board. The board boots
from SD/MMC. Ethernet and USB host is supported.
