Don't populate the array max_mm_current_percent on the stack, instead
make it static const. Makes the object code smaller by over 280 bytes:
Before:
text data bss dec hex filename
7225 1936 64 9225 2409 ./drivers/leds/leds-aat1290.o
After:
text data bss dec hex filename
6847 2032 64 8943 22ef ./drivers/leds/leds-aat1290.o`
