Subject: [PATCH 01/11] devicetree: bindings: Document cpu enable-method for ARM CPUs

From: Rohit Vaswani <rvaswani@...eaurora.org>

According to the ePAPR CPUs should have an enable method. On ARM
the enable-method property has not been used so far, so document
this property as an optional property and add the spin-table
method as one value
