leds: Make default trigger fields const
The default_trigger fields of struct gpio_led and thus struct led_classdev are pretty much always assigned from a string literal, which means the string can't be modified. Which is fine, since there is no reason to modify the string and in fact it never is. But they should be marked const to prevent such code from being added, to prevent warnings if -Wwrite-strings is used, when assigned from a constant string other than a string literal (which produces a warning under current kernel compiler flags), and for general good coding practices.
