[PATCH] Add regmap support

[Sascha Hauer]

This series adds simple regmap support. It's overdue to have regmap
support in barebox since regmap can make register accesses far more
generic and convenient. More and more kernel code depends on it, so
here it is for barebox. Two drivers are switched over to regmap to
provide some users.
