leds: pca955x: Cleanup OF/ID table terminators

Some cleanups:
 * Remove the trailing comma in the terminator entry for the OF
   table making code robust against (theoretical) misrebases or other
   similar things where the new entry goes _after_ the termination without
   the compiler noticing.
 * Drop a space from terminator entry for ID table.

While at it, move OF/ID table near to the user.
