[PATCH v3 3/3] arm64: dts: rockchip: Add Axelera Embedded 111c

[Patrick Barsanti <patrick.barsanti@amarulasolutions.com>]

Add minimal device tree for the Axelera Embedded 111c
(rk3588-axelera-embedded-111c).

It offers efficient AI compute for multi-stream computer vision and
GenAI applications in a compact design. It features a quad-core
Axelera AI Metis AIPU and an RK3588 SoC processor.

This basic version of the dts supports:
- Console
- eMMC
- HDMI
- 4x USB-A
- 2x Gigabit Ethernet
- RTC
- Enumeration of on-board Axelera Metis AIPU

Changes in v3:
- Rename from rk3588-embedded-111c.dts to
  rk3588-axelera-embedded-111c.dts
- Drop deprecated "regulator-suspend-microvolt" property
- Add Co-developed-by to the sign-off chain from Michael and Dario.
  (The process was: the first version of the downstream dts for the
  Rockchip kernel we've been using since 2024 was authored by Michael
  with some of my help. The first version of this upstream dts was
  co-developed by Dario and Michael together and in-person at a
  workshop. Later on this was picked up by me and largely
  re-written, but without their contribution and their prior work this
  series would not exist. I hope having all three of us as
  Co-developers on this patch, given the particular circumstances,
  is alright :))
- Add Copyright from Amarula Solutions

Changes in v2:
- Prepend "regulator-" to regulator nodes
- Drop non-existent "mem-supply" binding
- Drop unneeded comment from rgmii-rxid; replace it with the one from
  rk3588-youyeetoo-yy3588 to stop checkpatch from complaining
- Remove phy reset from the gmac node; note that these are still not
  described in the phy node because GPIO3_B7 defaults to pull-down,
  which causes the rgmii_phy1 node to never come up.
  Describing the reset in the parent mdio node instead does not cause
  the same issue
- Use the existing hdmim1_tx0_hpd pinctrl group instead of
  redefining it
- Drop "full-pwr-cycle-in-suspend" from the eMMC node
- Add "vmmc-supply" and "vqmmc-supply" to the eMMC node
- Add pinctrl for the pmic interrupt pin
- Replace the "vcc3v3_hubreset" regulator hack with two GL3523 hubs
  linked with "peer-hub".
- Drop the regulators that were defined but never referenced, and their
  corresponding pinctrls
- Mux PCIEX4_PERST_N as GPIO, since it is being used as reset-gpios
- Drop unused input.h include
- Drop unused rtc label
- Drop the local pciex1 pinctrl groups, as they were duplicates of the
  pcie30x1m1_1_* groups in the base pinctrl for the rk3588
