[PATCH v8 2/3] arm64: dts: marvell: Add Armada 98DX2530 SoC and RD-AC5X board

The 98DX2530 SoC is the Control and Management CPU integrated into
the Marvell 98DX25xx and 98DX35xx series of switch chip (internally
referred to as AlleyCat5 and AlleyCat5X).

Notes:
The Marvell SDK has a number of new compatible strings. I've brought
through some of the drivers or where possible used an in-tree
alternative (e.g. there is SDK code for a ac5-gpio but two instances of
the existing marvell,orion-gpio seems to cover what is needed if you use
an appropriate binding). I expect that there will a new series of
patches when I get some different hardware (or additions to this series
depending on if/when it lands).
Changes in v8:
- Remove unnecessary clock-frequency property on armv8-timer
- Remove unnecessary redistributor-stride property on gic
- Add GIC_SPI interrupts for gpios
Changes in v7:
- Add missing compatible on usb1
- Add "rd-ac5x" compatible for board
- Move aliases to board dts
- Move board specific usb info to board dts
- Consolidate usb1 board settings and remove unnecessary compatible
- Add Allied Telesis copyright
- Rename files after mailng-list discussion
Changes in v6:
- Move CPU nodes above the SoC (Krzysztof)
- Minor formatting clean ups (Krzysztof)
- Run through `make dtbs_check`
- Move gic nodes inside SoC
- Group clocks under a clock node
Changes in v5:
- add #{address,size}-cells property to i2c nodes
- make i2c nodes disabled in the SoC and enable them in the board
- add interrupt controller attributes to gpio nodes
- Move fixed-clock nodes up a level and remove unnecessary @0
Changes in v4:
- use 'phy-handle' instead of 'phy'
- move status="okay" on usb nodes to board dts
- Add review from Andrew
Changes in v3:
- Move memory node to board
- Use single digit reg value for phy address
- Remove MMC node (driver needs work)
- Remove syscon & simple-mfd for pinctrl
Changes in v2:
- Make pinctrl a child node of a syscon node
- Use marvell,armada-8k-gpio instead of orion-gpio
- Remove nand peripheral. The Marvell SDK does have some changes for the
ac5-nand-controller but I currently lack hardware with NAND fitted so
I can't test it right now. I've therefore chosen to omit the node and
not attempted to bring in the driver or binding.
- Remove pcie peripheral. Again there are changes in the SDK and I have
no way of testing them.
- Remove prestera node.
- Remove "marvell,ac5-ehci" compatible from USB node as
"marvell,orion-ehci" is sufficient
- Remove watchdog node. There is a buggy driver for the ac5 watchdog in
the SDK but it needs some work so I've dropped the node for now.
