arm64: Slightly improve the warning on CPU0 enable-method
Commit e8765b265a69 (arm64: read enable-method for CPU0) introduced checks for the enable method on CPU0 (to be later used with CPU suspend). However, if the kernel is compiled for UP and a DT file is used with a method like 'spin-table', Linux complains about 'invalid enable method'. This patch turns it into an 'unsupported enable method' warning.
