loongarch, mips, parisc, riscv and sh all print a warning if
register_cpu() returns an error. Architectures that use
GENERIC_CPU_DEVICES call panic() instead.

Errors in this path indicate something is wrong with the firmware
description of the platform, but the kernel is able to keep running.

Downgrade this to a warning to make it easier to debug this issue.

This will allow architectures that switching over to GENERIC_CPU_DEVICES
to drop their warning, but keep the existing behaviour.
