Subject: [PATCH] clkdev: Update clkdev id usage to allow for longer names

clkdev ID information is limited to arrays of 20 and 16 bytes
(MAX_DEV_ID/MAX_CON_ID).  It is possible that the IDs could be
longer that.  If so, the lookup will fail because the "real ID"
will not match the copied value.

Increase the size of the IDs to allow for longer names.
