[RFC 1/3] of: make of_mutex public

[wsa@the-dreams.de (Wolfram Sang)]

From: Wolfram Sang <wsa+renesas@sang-engineering.com>

If we want to use OF_DYNAMIC features outside the of framework, we need
to access this lock. If OF maintainers don't like exporting, we can
maybe create accessor functions that we can use?
