Make LEDS_LP55XX_COMMON depend on I2C to fix build errors:

leds-lp55xx-common.c:(.text+0x9d): undefined reference to `i2c_smbus_read_byte_data'
leds-lp55xx-common.c:(.text+0x8fc): undefined reference to `i2c_smbus_write_byte_data'

These errors happened when I2C=m and LEDS_LP55XX_COMMON=y, so
prevent that from being possible.
