Add my old and new work email mapping and use work email to support acpi

Updating mailmap to indicate ani@anisinha.ca and anisinha@redhat.com are one
and the same person. Also updating my email in MAINTAINERS for all my acpi work
(reviewing patches and biosbits) to my work email. Also doing the same for
bios bits test framework documentation.
