ARM: dts: qcom: apq8060: Correct Ethernet node name and drop bogus irq property

make dtbs_check:

ethernet-ebi2@2,0: $nodename:0: 'ethernet-ebi2@2,0' does not match '^ethernet(@.*)?$'
ethernet-ebi2@2,0: 'smsc,irq-active-low' does not match any of the regexes: 'pinctrl-[0-9]+'

There is no "smsc,irq-active-low" property, as active low is the
default.
