Add test_arm_raspi4_rng_thermal, exercising the raspi4b RNG200 and
thermal sensor devices added in this series: boot, confirm the
RNG200 driver probes it ("hwrng registered" in the kernel log),
reach a shell, and confirm the thermal zone reports the expected
fixed reading and /dev/hwrng actually yields data rather than just
existing.Verified locally against this series with the exact kernel/initrd assets this file already pins.
