[PATCH] leds: fix module build error for LP55xx common driver

[Kim, Milo]

To solve undefined symbol errors for LED class and I2C, lp55xx-common driver
should support a module build as well.

make x86_64 allmodconfig failed like this:

drivers/built-in.o: In function `lp55xx_unregister_leds':

drivers/built-in.o: In function `lp55xx_init_led':
