leds: blinkm: Fix CONFIG_LEDS_CLASS_MULTICOLOR dependency
With CONFIG_LEDS_CLASS_MULTICOLOR=m, a builtin leds-blinkm driver causes
a link failure:
arm-linux-gnueabi-ld: drivers/leds/leds-blinkm.o: in function `blinkm_set_mc_brightness':
leds-blinkm.c:(.text.blinkm_set_mc_brightness+0xc): undefined reference to `led_mc_calc_color_components'
Add a more specific dependency that only allows multicoler mode to
be enabled for blinkm if it can build and link.
Fixes: 56e8c56c9af0 ("leds: Add multicolor support to BlinkM LED driver")
