Introduces kobject support for the common struct clk, exports per-clk
data via read-only callbacks and models the clk tree topology in sysfs.

Also adds support for generating the clk tree in clk_init and migrating
nodes when input sources are switches in clk_set_parent.

Since this introduces a new top-level hierarchy in sysfs, it certainly needs
to be reviewed by Greg K-H (on Cc now). Also, you have to add a proper
documentation for every new node and attribute in Documentation/ABI along
with the code.

+static struct kobject *clk_kobj;
+LIST_HEAD(kobj_list);

The list head should be static.
