clkdev: Update clkdev id usage to allow for longer names

BugLink: https://bugs.launchpad.net/bugs/2074091
commit 99f4570cfba1e60daafde737cb7e395006d719e6 upstream.

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.
