v2024.05.0 zynqmp kernels get random mac address for eth0 on each boot

[wmamills]

kv260 and zcu102 (HW & QEMU) get a random mac address at the kernel level each boot cycle.
The u-boot level has the correct mac address.
This is a know failure on zynqmp when things are not configured correctly.
It is believed that v6.6.y kernel builds have NOT shown this issue but the exact kconfig and value of ".y" needs to be investigated and proper operation need to be re-asserted.

Do to the nature of QEMU user networking DHCP server, the first boot in the emulator will get the correct/expected 10.0.2.15 address.
HOWEVER if the user does a "shutdown -r now" the next boot will get 10.0.2.16 and the preset config for host pane "ssh qemu-zcu102" won't work.

On real HW the user will have to query the IP address each boot if they wish to use ssh.
