Subject: [PATCH 7/8] arm64: dts: axiado: add common sdhci host node in dtsi

From: SriNavmani A <srinavmani@...ado.com>

Add the SDHCI host controller device tree node to the AX3000 SoC
device tree include file. This node defines the Arasan eMMC host
controller configuration, including register mappings, interrupts,
and clock references for the AX3000 SoC.
