clk: sifive: Do not register clkdevs for PRCI clocks

Browse source 
[ Upstream commit 2607133196 ]

These clkdevs were unnecessary, because systems using this driver always
look up clocks using the devicetree. And as Russell King points out[1],
since the provided device name was truncated, lookups via clkdev would
never match.

Recently, commit 8d532528ff ("clkdev: report over-sized strings when
creating clkdev entries") caused clkdev registration to fail due to the
truncation, and this now prevents the driver from probing. Fix the
driver by removing the clkdev registration.
