For devices without a dedicated 'diag' LED, we use sometimes one of
other LEDs for indicating at least 'boot', 'failsafe' and 'upgrade'
stages. In some cases, at the same time these LEDs have defined default
triggers in DTS using 'linux,default-trigger' property. Current 'diag'
setup removes the trigger and turns off 'boot' LED after bootup.
One of the examples of such device is TP-Link TL-WR841N v14 (ramips)
which uses 'wlan' LED with defined 'linux,default-trigger' for 'diag':
aliases {
led-boot = &led_wlan;
led-failsafe = &led_wlan;
led-upgrade = &led_wlan;
};
[...]
led_wlan: wlan {
label = "tl-wr841n-v14:green:wlan";
gpios = <&gpio1 9 GPIO_ACTIVE_LOW>;
linux,default-trigger = "phy0tpt";
};
This patch extends 'diag.sh' and 'leds.sh' scripts to make sure default
trigger defined in DTS is restored for 'diag' LED which isn't used for
indicating 'running' stage.

I wanted to add status LEDs support to my imx6 based board and have
found out, that I could use diag.sh script found in ramips platform,
which seems to be also shared in a few other platforms:
4801276bc2078c5bcf03003c831e3b0a target/linux/ramips/base-files/etc/diag.sh
4801276bc2078c5bcf03003c831e3b0a target/linux/ipq40xx/base-files/etc/diag.sh
4801276bc2078c5bcf03003c831e3b0a target/linux/ath79/base-files/etc/diag.sh
So I've extended the base diag.sh in a way, that if it detects any of
the DTS LED aliases, then it would use the generic DTS set_led_state
code.
