leds: leds-cros_ec: Skip LEDs without color components
A user reports that on their Lenovo Corsola Magneton with EC firmware
steelix-15194.270.0 the driver probe fails with EINVAL. It turns out
that the power LED does not contain any color components as indicated
by the following "ectool led power query" output:
Brightness range for LED 1:
red : 0x0
green : 0x0
blue : 0x0
yellow : 0x0
white : 0x0
amber : 0x0
The LED also does not react to commands sent manually through ectool and
is generally non-functional.
Instead of failing the probe for all LEDs managed by the EC when one
without color components is encountered, silently skip those.
