Should it not be CONFIG_PM_SLEEP instead of just CONFIG_PM?

Why? I think we should have CONFIG_PM_SLEEP only when we have
*suspend*, *resume* hooks. But this driver has only *runtime_suspend*
and *runtime_resume* hooks.

Yes, you are right. CONFIG_PM_SLEEP is not needed for runtime.

Do you really need arch_initcall here?
If not, then you can replace above two function calls with

module_platform_driver().

I indeed want it to be arch_initcall. When the module is built-in, I
want this module to loaded before twl6030-usb.c

Should be fine.
