One fix for the SiFive PRCI clocks so that the device boots again. This

driver was registering clkdev lookups that were always going to be
 useless. This wasn't a problem until clkdev started returning an error
 in these cases, causing this driver to fail probe, and thus boot to fail
 because clks are essential for most drivers. The fix is simple, don't
 use clkdev because this is a DT based system where clkdev isn't used.
