[ Upstream commit 2607133196c35f31892ee199ce7ffa717bea4ad1 ]
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 8d532528ff6a ("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.
