dibs: Use subsys_initcall()

In the case of built-in modules, the order of module_init() calls are
derived from the Makefiles.

Use subsys_initcall() for the dibs module, to make sure dibs_init() is
executed before dibs clients like smc and dibs devices like ism are
initialized. So future dibs client or dibs device modules can use
module_init() without the risk of getting the order in the Makefiles wrong.
