leds: lp5562: make several arrays static const
Don't populate the arrays on the stack, instead make them static const.
Makes the object code smaller by over 150 bytes:
Before:
text data bss dec hex filename
7725 2448 64 10237 27fd drivers/leds/leds-lp5562.o
After:
text data bss dec hex filename
7184 2832 64 10080 2760 drivers/leds/leds-lp5562.o
