[PATCH] powerpc: Remove device_type = "rtc" properties in .dts files

[Matt Sealey]

I'm extremely troubled that it is "not used in the code", 
surely device_type is checked as a legacy for Open Firmware 
(otherwise a lot of devices may never be detected!), or does 
device tree parsing/checking follow a different path for FDT?

(absolutely fine with it being removed from new DTS but, just 
concerned about your comment and it's impact...)
