LED core provides a helper to parse default state from firmware node.
Use it instead of custom implementation.

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.

By using struct led_init_data when registering we do not need to parse
`label` DT property. Moreover `label` is deprecated and if it is not
present but `color` and `function` are, LED core will compose a name
from these properties instead.

These two drivers do not provide remove method and use devres for
allocation of other resources, yet they use led_classdev_register
instead of the devres variant, devm_led_classdev_register.
Fix this.

This lock isn't really needed, since we're only reading the register and
changes made to other LEDs aren't relevant.

Replaces bcm6358_led_mode with bcm6358_led_set so we don't need to handle
the lock.

for_each_available_child_of_node performs an of_node_get on each
iteration, so a break out of the loop requires an of_node_put.
A simplified version of the semantic patch that fixes this problem is as
follows (http://coccinelle.lip6.fr):
// <smpl>
@@
expression root,e;
local idexpression child;
@@
for_each_available_child_of_node(root, child) {
... when != of_node_put(child)
when != e = child

return child;

+ of_node_put(child);
? return ...;
