gpio: pl061: Support building as module
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.
