[RFC PATCH devicetree 07/10] arm64: dts: ls208xa: rename the "interrupt-map" of the extirq node to "fsl,extirq-map"

[Vladimir Oltean]

In the discussions here:
https://lore.kernel.org/all/CAMuHMdXM34nNz1nfowNqDvdsdg+d69Bo3_ufs6fbcq65iYd5-A@xxxxxxxxxxxxxx/T/#m3449390080c5a0c8f59b8f8286a87e31e093b98b
Marc Zyngier points out that the ls-extirq driver should have never used
the "interrupt-map" keyword for mapping its channels to GIC interrupts.

This change modifies the device trees for the LS2 family of devices to
use a driver-specific OF property for that purpose. The change is
intended to target stable kernels, to accelerate the conversion and
ultimate removal of the improperly used "interrupt-map" property.

Note that "interrupt-map-mask" isn't needed now (nor was it needed
before, it was just there to keep an apparent compatibility in form with
the reserved "interrupt-map" property). So delete it.
