Update MAINTAINERS, add OWNERS

Replace IRC with Discord since the community doesn't use IRC anymore.
Update discord name for Matt and George.

Add Brandon as Reviewer, he's written much of the next generation power
code (phosphor-power-supply) including psu monitoring and gpio handling.

The OWNERS file allows gerrit to automatically CC the owners on a review
when it's pushed, removing the need to add maintainers manually.

Eventually the MAINTAINERS file can be deprecated. For now keep both
until it's removed project-wide in openbmc.

+# OWNERS
+# ------
+#
+# The OWNERS file maintains the list of individuals responsible for various
+# parts of this repository, including code review and approval.  We use the
+# Gerrit 'owners' plugin, which consumes this file, along with some extra
+# keywords for our own purposes and tooling.
+#
+# For details on the configuration used by 'owners' see:
+#  https://gerrit.googlesource.com/plugins/owners/+/refs/heads/master/owners/src/main/resources/Documentation/config.md
+#
+# An OWNERS file must be in the root of a repository but may also be present
+# in any subdirectory.  The contents of the subdirectory OWNERS file are
+# combined with parent directories unless 'inherit: false' is set.
+#
+# The owners file is YAML and has [up to] 4 top-level keywords.
+#   * owners: A list of individuals who have approval authority on the
+#     repository.
+#
+#   * reviewers: A list of individuals who have requested review notification
+#     on the repository.
+#
+#   * matches: A list of specific file/path matches for granular 'owners' and
+#     'reviewers'.  See 'owners' plugin documentation.
+#
+#   * openbmc: A list of openbmc-specific meta-data about owners and reviewers.
+#     - name: preferred name of the individual.
+#     - email: preferred email address of the individual.
+#     - discord: Discord nickname of the individual.
+#
+# It is expected that these 4 sections will be listed in the order above and
+# data within them will be kept sorted.
