The clock references could also be retrieved via clk_get_sys(). We could add
some more clkdev entries. If we use the domain name as the dev_id and the
module names as the con_id's, the domain code could then retrieve the
clocks by iterating over the module names and performing a
clk_get_sys(domain_name, module_name) for each module. Unfortunately no such
mechanism exists for resets.

Cheers,

Peter.
