Subject: [PATCH] arm64: dts: freescale: imx93-phycore-som: Remove "fsl,magic-packet"

FEC WoL (Wake-on-Lan) functionality depends on using Ethernet PHY in IRQ
mode. However, on phyCORE-i.MX93 SoM, polling mode is used instead for
the FEC Ethernet PHY. Consequently, WoL is non-functional. Thus disable
it by removing "fsl,magic-packet" property. This allows us to save some
power during device suspend as PHY is not kept awake.
