AMU: Remove unnecessary WARN()
If AMU is not supported by the hardware but it is enabled in Trusted
Firmware, the console will be spammed with warnings every time a CPU
is brought up with a CPU ON call.
Remove the warning message as this is more in line with how other
extensions like SPE and SVE are handled.
