leds: lp5521: 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 120 bytes:
Before:
text data bss dec hex filename
8999 4176 64 13239 33b7 drivers/leds/leds-lp5521.o
After:
text data bss dec hex filename
8554 4496 64 13114 333a drivers/leds/leds-lp5521.o
