This fixes booting RPi3+4 with the in-review spintable patch; rpi3-psci-monitor patches the FDT to add a PSCI node, but it doesn't patch each cpus' enable-method. Because of this, we would stall the boot while enabling CPU 1 as we saw a valid looking enable-method and "no" functional PSCI and attempted to use the spintable rather than simply not starting secondary APs.

Do this now, so we can use it to decide if enable-method in /cpus FDT nodes should be inspected later on. While we're here, convert it to a boolean.

This interface will also be used by Intel Stratix 10 platform. This was not tested on arm due to lack of PSCI-enabled arm hardware lying around.

As this may have a large performance overhead, and how exploitable SSBD is is unknown we follow the Linux lead of allowing the administrator to select between always on, always off, or only enabled in the kernel, with the latter being the default.
