leds: cht-wcove: Use breathing when LED_INIT_DEFAULT_TRIGGER is set

The desired default behavior of LED1 / the charge LED is breathing
while charging and on/solid when full. Since triggers cannot select
breathing, blink_set() gets called when charging. Use breathing
when the default "charging-blink-full-solid" trigger is used to
achieve the desired default behavior.
