leds: aw2013: Select missing dependency REGMAP_I2C

The AW2013 driver uses devm_regmap_init_i2c, so REGMAP_I2C needs to
be selected.

Otherwise build process may fail with:
  ld: drivers/leds/leds-aw2013.o: in function `aw2013_probe':
    leds-aw2013.c:345: undefined reference to `__devm_regmap_init_i2c'
