ARM: dts: bcm283x: Move ACT LED into separate dtsi

The usage of the label property for gpio-leds has been deprecated
a long time ago. In bcm2835-rpi.dtsi the ACT LED uses such a label
and derive it to almost every Raspberry Pi board. Since we cannot break
userspace interface this property must be kept. But we can move the
ACT LED into a separate dtsi and include them from the board files.

This change have two benefits:
- with both new refs it's now clear the LED part is included from a dtsi
- new boards do not include the deprecated stuff automatically
