The opp-v1 binding is only used in MIPS and arm32 CPU nodes, so add a $ref to it in the CPU schemas and drop the "select". As opp-v1 has long been deprecated, mark it as such.

The device tree allows to describe the layout of CPUs in a system through
|
|
the "cpus" node, which in turn contains a number of subnodes (ie "cpu")
|
|
defining properties for every CPU.
