There is another reason they would never match - clkdev has always been
about matching the clock _consumer_ using the device name and connection
name to the producer. The device and connection name passed into clkdev
should always be the consumer (it's documented as such.)

Providing the producer device name to clkdev when registering an entry
will mean that clk_get(consumer_dev, consumer_name) will fail to find
the entry in clkdev's table, and thus fail to find the clock.

So, this code has been incorrect from the very start.
