OMAP: hwmod: Handle opt clocks node using clk_add_alias
For every optional clock present per hwmod per omap-device, this function adds an entry in the clocks list of the form <dev-id=dev_name, con-id=role>, if an entry is already present in the list of the form <dev-id=NULL, con-id=role>. The function is called from within the framework inside omap_device_build_ss(), after omap_device_register. This allows drivers to get a pointer to its optional clocks based on its role by calling clk_get(<dev*>, <role>).
