[PATCH v2 1/3] qdev-properties: Accept bool for OnOffAuto

[Akihiko Odaki <akihiko.odaki@daynix.com>]

Accept bool literals for OnOffAuto properties for consistency with bool
properties. This enables users to set the "on" or "off" value in a
uniform syntax without knowing whether the "auto" value is accepted.
This behavior is especially useful when converting an existing bool
property to OnOffAuto or vice versa.
