Create an interface for drivers to enable or disable their clocks as listed

in the clocks=<...> properties of their FDT data. The clock properties consist of 2-cell tuples, each containing a clock device node reference and a clock number. A clock device driver can register itself as providing this interface, then other drivers can turn the FDT clock node reference into the corresponding device_t so that they can use the interface to query and manipulate their clocks. This provides convenience functions to enable or disable all the clocks listed in the properties for a device, so most drivers will be able to manage their clocks with a single call to fdt_clock_enable_all(dev).
