Do parsing of `linux,default-trigger` DT property to LED core. Currently it is done in many different drivers and the code is repeated. This patch removes the parsing from 21 drivers: an30259a, aw2013, bcm6328, bcm6358, cr0014114, el15203000, gpio, is31fl319x, is31fl32xx, lm3532, lm36274, lm3692x, lm3697, lp8860, lt3593, max77650, mt6323, ns2, pm8058, tlc591xx and turris-omnia. There are still 11 drivers that parse this property on their own because they do not pass the led_init_data structure to the registering function. I will try to refactor those in the future.
