of: base: Skip CPU nodes with "fail"/"fail-..." status Allow fully disabling CPU nodes using status = "fail". This allows a bootloader to change the number of available CPUs (for example when a common DTS is used for SoC variants with different numbers of cores) without deleting the nodes altogether, which could require additional fixups to avoid dangling phandle references. Unknown status values (everything that is not "okay"/"ok", "disabled" or "fail"/"fail-...") will continue to be interpreted like "disabled", meaning that the CPU can be enabled during boot.
