Do the 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 23 drivers:
an30259a, aw2013, bcm6328, bcm6358, cr0014114, el15203000, gpio,
is31fl32xx, lm3532, lm36274, lm3692x, lm3697, lp50xx, lp8860, lt3593,
max77650, mt6323, ns2, pm8058, pwm, syscon, tlc591xx and turris-omnia.
There is one driver in drivers/input which parses this property on it's
own. I shall send a separate patch there after this is applied.
There are still 8 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.

Various drivers count and iterate over OF children nodes via
of_get_child_count and for_each_child_of_node. Instead they should use
of_get_available_child_count and for_each_available_child_of_node, so
that if a given node has the `status` property set to `disabled`, the
child will be ignored.

The dev_of_node function should be preferred.

an30259a_probe misses a check for devm_regmap_init_i2c and may cause
problems.
Add a check and print errors like other leds drivers.

All this file is about an30259a, including the reference to the datasheet
at the top of the file.
So change the 2 places where an32059a is used instead.

AN30259A is a 3-channel LED driver which uses I2C. It supports timed
operation via an internal PWM clock, and variable brightness. This
driver offers support for basic hardware-based blinking and brightness
control.
