arm64: dts: ti: k3-am62p: use eFuse MAC Address for CPSW3G Port 1

Browse Source 
Add the "ethernet-mac-syscon" node within "wkup_conf" node corresponding to
the CTRLMMR_MAC_IDx registers within the CTRL_MMR space. Assign the
compatible "ti,am62p-cpsw-mac-efuse" to enable "syscon_regmap" operations
on these registers. The MAC Address programmed in the eFuse is accessible
through the CTRLMMR_MAC_IDx registers. The "ti,syscon-efuse" device-tree
property points to the CTRLMMR_MAC_IDx registers, allowing the CPSW driver
to fetch the MAC Address and assign it to the network interface associated
with CPSW3G MAC Port 1.
