This pull request contains Broadcom ARM64-based SoCs Device Tree updates
for 6.18, please pull the following:

- Krzysztof fixes a DTC warning for the ARM GIC in bcm2712.dtsi

- Ivan adds the pin controller node(s), an additional GPIO controller,
  the second SDHCI controller node for SDIO Wi-Fi, and the UARTA for
  Bluetooth to the BCM2712 DTS (Raspberry Pi 5)

- Stanimir adds the Ethernet DT node and enables it for the RP1 sister
  chip

- Andrea deletes a number of redundant PCIe DT node enablement, updates
  a comment to describe the relationship between bcm2712 and RP1 and
  finally enables the USB controllers with RP1
