RPI1 (armv6h) kernel frequency scaling disabled.

[keithspg]

Been running Arch Arm for a while on RPi1 and 2/3/4. With the update to kernel 5.4.x, I get a panic that appears on the Armv6 variant. It does not appear on the pi2/3/4 variant. Raspbian https://github.com/raspberrypi/linux/issues/3637 does not seem to have it. The kernel will boot, but this shows on my old Pi1s and my PiZeros at every reboot and it does not scale frequency.
