This holds mac-address which is at least 48bits long

This adds new dtbs_check warnings:

+/workdir/arch/arm64/boot/dts/ti/k3-am62p5-sk.dtb: syscon at 100000: $nodename:0: 'syscon at 100000' does not match '^([a-z][a-z0-9\\-]+-bus|bus|localbus|soc|axi|ahb|apb)(@.+)?$'
+/workdir/arch/arm64/boot/dts/ti/k3-am62p5-sk.dtb: syscon at 200: compatible: ['syscon', 'simple-mfd'] is too short
+/workdir/arch/arm64/boot/dts/ti/k3-am62p5-sk.dtb: syscon at 4008: compatible: ['syscon', 'simple-mfd'] is too short
+/workdir/arch/arm64/boot/dts/ti/k3-am62p5-sk.dtb: syscon at 4018: compatible: ['syscon', 'simple-mfd'] is too short


I suggest to drop them for now.

Please add a new yamls for these nodes or single yaml for top level wkup_conf to 
cover am62/62a/62p SoCs and then introduce the nodes accordingly
