[PATCH] Add 'hotpluggable' property for /memory nodes

[PATCH] Add 'hotpluggable' property for /memory nodes

[Rob Herring]

The 'hotpluggable' property has been documented and supported in the Linux
kernel since 2016. Add the property to the spec so we can remove the kernel
specific documentation.
