arm64: dts: ti: k3-am62-phycore-som: Add bootphase tag to cpsw_mac_syscon

Add the "bootph-all" boot phase property to cpsw_mac_syscon.

This fuse region contains the internal MAC address. Without this
syscon node enabled, this interface will get a random MAC during
network boot. This is problematic because the AM62x network
boot is using BOOTP protocol for some binaries and this protocol
does not support dynamic lease expiration. Therefore, the DHCP
server can run out of free IP addresses.
