The current implementation of Alan's bridge driver is using regmap to
toggle the reset manager bits. However, that required adding "syscon" to
the reset manager's DTS node. By doing this, the reset driver was not
able to load.
So that's the story behind why I'm looking to convert Alan's bridge
driver to use the reset driver.
