[PATCH 2/2] rules: add ID_EXTERNAL_PORT and ID_MODEM

[Linus Walleij <linus.walleij@xxxxxxxxxx>]

Distributions doing desktop spins or other single-user systems
may be interested in enabling access to the external ports (serial,
USB-to-serial dongle etc) and modems for the logged-in user.

To help with this, mark external serial ports with
ID_EXTERNAL_PORT and modems with ID_MODEM. This way a distributor
can create a 60-desktop-acl.rules (or similarly named) file like
this:

ENV{ID_EXTERNAL_PORT}=="*?", TAG+="udev-acl"
ENV{ID_MODEM}=="*?", TAG+="udev-acl"

To enable local access to external ports and modems on these
specific distributions.
