clkdev: Update clkdev id usage to allow for longer names
clkdev DEV ID information is limited to an array of 20 bytes
(MAX_DEV_ID). It is possible that the ID could be longer than
that. If so, the lookup will fail because the "real ID" will
not match the copied value.
For instance, generating a device name for the I2C Designware
module using the PCI ID can result in a name of:
i2c_designware.39424
clkdev_create() will store:
i2c_designware.3942
The stored name is one off and will not match correctly during probe.
Increase the size of the ID to allow for a longer name.
