[PATCH v2 12/40] docs: usb: Use ASCII subset instead of UTF-8 alternate symbols

[Mauro Carvalho Chehab]

The conversion tools used during DocBook/LaTeX/Markdown->ReST conversion
and some automatic rules which exists on certain text editors like
LibreOffice turned ASCII characters into some UTF-8 alternatives that
are better displayed on html and PDF.

While it is OK to use UTF-8 characters in Linux, it is better to
use the ASCII subset instead of using an UTF-8 equivalent character
as it makes life easier for tools like grep, and are easier to edit
with the some commonly used text/source code editors.

Also, Sphinx already do such conversion automatically outside literal blocks:
   https://docutils.sourceforge.io/docs/user/smartquotes.html

So, replace the occurences of the following UTF-8 characters:

	- U+201c ('“'): LEFT DOUBLE QUOTATION MARK
	- U+201d ('”'): RIGHT DOUBLE QUOTATION MARK
	- U+feff (''): ZERO WIDTH NO-BREAK SPACE
