arm64: dts: uniphier: Use GIC interrupt definitions

Use human-readable definitions for GIC interrupt type and flag, instead of
hard-coding the numbers. No functional change.

arm64: dts: uniphier: Rename gpio-hog nodes

According to gpio-hog schema, should add the suffix "-hog" to the node
names including gpio-hog to fix the following warning.

uniphier-ld11-ref.dtb: gpio@55000000: 'xirq0' does not match any of the regexes: '^.+-hog(-[0-9+)?$', 'pinctrl-[0-9]+'
From schema: Documentation/devicetree/bindings/gpio/socionext,uniphier-gpio.yaml

This applies to the devicetre for LD11, LD20 and PXs3 SoCs.

arm64: dts: uniphier: add interrupts to support card serial

Since commit e69f5dc623f9 ("dt-bindings: serial: Convert 8250 to
json-schema"), the schema for "ns16550a" is checked.

Since then, 'make ARCH=arm64 dtbs_check' is so noisy because the
required property 'interrupts' is missing.

arm64: dts: uniphier: Add ethernet aliases

Add 'aliases' properties for ethernet device.

U-Boot performs a fix-up of the MAC address and will overwrite the values
from the Linux devicetree for aliased ethernet device. The MAC address can
be inherited from U-Boot by adding aliases of ethernet devices.

arm64: dts: uniphier: stabilize ethernet of LD20 reference board

Currently, the ethernet RGMII mode on the LD20 reference board is
unstable.

The default drive-strength of ethernet TX pins is too strong because
there is no dumping resistor on the TX lines on the board.

Weaken the drive-strength to make the ethernet more stable.

arm64: dts: uniphier: use proper SPDX-License-Identifier style

According to Documentation/process/license-rules.rst, move the SPDX
License Identifier to the very top of the file. I used C++ comment
style not only for the SPDX line but for the entire block because
this seems Linus' preference [1]. I also dropped the parentheses to
follow the examples in that document.

arm64: dts: uniphier: remove unnecessary interrupt-parent

These were added to make the ARM64 branch self-contained because
updates for ARM and ARM64 are supposed to be sent as separate
pull requests.

Now, they were merged together in Linus' tree and interrupt-parent
from the arch/arm/boot/dts/uniphier-support-card.dtsi is visible from
ARM64 DT files by the cross-arch reference.

arm64: dts: uniphier: move memory node below aliases node

These UniPhier DT files are fine as long as they are compiled in the
Linux build system. It is true that Linux is the biggest user of
DT, but DT is project neutral from its concept. DT files are often
re-used for other projects. Especially for the UniPhier platform,
these DT files are re-used for U-Boot as well.

If I feed these DT files to the FDTGREP tool in U-Boot, it complains
about the node order.

FDTGREP spl/u-boot-spl.dtb
Error at 'fdt_find_regions': FDT_ERR_BADLAYOUT
/aliases node must come before all other nodes

Given that DT is not very sensitive to the order of nodes, this is a
problem of FDTGREP. I filed a bug report a year ago, but it has not
been fixed yet.

Differentiating DT is painful. So, I am up-streaming the requirement
from the down-stream project.

arm64: dts: uniphier: match DT names to other projects and documents

All UniPhier device trees have the common prefix "uniphier-", so
"ph1-" is just making names longer. Recent documents and other
projects are not using PH1- prefixes any more.
