gpio: pl061: Support building as module (61684440) · Commits · 戴 / test

Enable building the PL061 GPIO driver as a module. This does change the initcall level when built-in. This shouldn't be a problem as any user should support deferred probe by now. A scan of DT based platforms at least didn't reveal any users that would be a problem.
