[PATCH 14/22] docs: arm64: convert perf.txt to ReST format

[Mauro Carvalho Chehab]

This file is almost in ReST. All it needs is a rename and
adding a :field: for the two fields at the beginning
(author and date).

While here, add a proper SPDX header, and use the standard
markup for document titles, just for consistency.
