base-files: diag.sh: Make it more generic towards DTS so it could be reused

Browse source 
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.
