Subject: [PATCH] Documentation: dt-bindings: Fix incorrect statement

It's found when reading the Doc.

In a SMP system, the hierarchy of CPUs now can be defined through
four not three entities (socket/cluster/core/thread), so correct
the statement to avoid possible confusion.

Since we are already there, also drop an extra space and tweak
the title alignment. No real context change at all.
