Convert the Devicetree binding documentation for:
* SUNW,n2-rng
* SUNW,vf-rng
* SUNW,kt-rng
* ORCL,m4-rng
* ORCL,m7-rng
from plain text to YAML.

-HWRNG support for the n2_rng driver

-Required properties:
-- reg		: base address to sample from
-- compatible	: should contain one of the following
-	RNG versions:
-	- 'SUNW,n2-rng' for Niagara 2 Platform (SUN UltraSPARC T2 CPU)
-	- 'SUNW,vf-rng' for Victoria Falls Platform (SUN UltraSPARC T2 Plus CPU)
-	- 'SUNW,kt-rng' for Rainbow/Yosemite Falls Platform (SUN SPARC T3/T4), (UltraSPARC KT/Niagara 3 - development names)
-	more recent systems (after Oracle acquisition of SUN)
-	- 'ORCL,m4-rng' for SPARC T5/M5
-	- 'ORCL,m7-rng' for SPARC T7/M7
