Documentation: embargoed-hardware-issues.rst: minor cleanups and fixes

The embargoed-hardware-issues.rst file needed a bunch of minor grammar,
punctuation, and syntax cleanups based on feedback we have gotten over
the past few years.  The main change here is the term "silicon" being
used over "hardware" to differentiate between companies that make a chip
(i.e. a CPU) and those that take the chip and put it into their system.

No process changes are made here at all, only clarification for the way
the current process works.

All of these changes have been approved by a review from a large number
of different open source legal members, representing the companies
involved in this process.
