[PATCH v1 1/1] arm64: dts: freescale: imx8mm-var-dart-sonata: Fix PCIe PHY init

[Stefano Radaelli]

From: Stefano Radaelli <stefano.r@xxxxxxxxxxxxx>

The PCIe PHY times out during initialization on the DART-MX8M Mini
with the Sonata carrier, preventing PCIe device enumeration.

Add fsl,clkreq-unsupported to configure the PHY for operation without
CLKREQ# support. This makes the PHY driver clear AUX_EN_OVERRIDE,
allowing PHY initialization to complete.

Fixes: 770aba46ea0f ("arm64: dts: imx8mm-var-dart: Add support for Variscite Sonata board")
