leds: pca955x: Optimize probe LED selection
Previously, the probe function might do up to 32 reads and writes
to the same 4 registers to program the LED selection. Reduce this to
a maximum of 5 operations by accumulating the changes to the LED
selection and comparing with the previous value to write the
selection if different.
