RUBIK Pi 3 (https://rubikpi.ai/), a lightweight development board based on
Qualcomm Dragonwing™ QCS6490 platform, is the first Pi built on Qualcomm
AI platforms for developers.

This commit enables the following features:
    Works:
    - Bluetooth (AP6256)
    - Wi-Fi (AP6256)
    - Ethernet (AX88179B connected to UPD720201)
    - Two USB Type-A 3.0 ports (UPD720201 connected to PCIe0)
    - USB Type-A 2.0 port
    - USB Type-C
    - M.2 M-Key 2280 PCIe 3.0
    - FAN
    - RTC
    - 40PIN: I2C x1, UART x1

Changes in v7:
- Revert the changes made to PCIe1 in version V6.
- Change the ADSP firmware path to `qcom/qcs6490/Thundercomm/RubikPi3/adsp.mbn`.
- Link to v6: https://lore.kernel.org/all/20251115-rubikpi-next-20251114-v1-0-fc630dc5bb5d@thundersoft.com/

Changes in v6:
- Fix device tree formatting issues.
- Add firmware-name to QUPv3 nodes.
- An "Internal error: synchronous external abort" error occurred while
  executing the `qcom_pcie_clear_hpc` function in the PCIe1 RC. The following
  changes were rolled back(overriding the configuration in `kodiak.dtsi`):
  03e928442d46 arm64: dts: qcom: sc7280: Increase config size to 256MB for ECAM feature
- Replace the three monochrome LEDs with multicolor LEDs.
- The drive-strength value of the pins is modified uniformly.
