Although checkpatch changed the max-line-length default to 100 columns,
we still prefer 80 columns somewhere.

Use integer constants directly when building I2C messages for LED color
change command, instead of macros. The command is simple enough to
understand what is going on even without these names.

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.

Not-for-stable: untested, theoretical, insignificant leaks
The dev_of_node function should be preferred.

This adds basic support for LEDs on the front side of CZ.NIC's Turris
Omnia router.
There are 12 RGB LEDs. The controller supports HW triggering mode for
the LEDs, but this driver does not support it yet, and sets all the LEDs
defined in device-tree into SW mode upon probe.
This driver uses the multicolor LED framework.
