Add test_arm_raspi4_genet, exercising the raspi4b GENET controller
end to end: boot with a -nic bcm2838-genet device attached, confirm
the guest driver probes it ("GENET 5.0 EPHY" in the kernel log),
reach a shell, and confirm the link actually comes up
("ip link show eth0" reports LOWER_UP) rather than just that the
device exists.Verified locally against this series with the exact kernel/initrd assets this file already pins (raspberrypi-kernel_1.20230106-1 / groeck linux-build-test rootfs): without the "fix PHY autonegotiation-restart deadlock" patch earlier in this series, the link never comes up and this test would hang at the "ip link show eth0" step, so it also serves as a regression test for that fix.
