Add USER LED0-LED8, which are available on RZ/T2H EVK.
In addition, the header file inclusion has been moved into the common
rzt2h-n2h-evk-common.dtsi so that both RZ/T2H and RZ/N2H EVK DTS/I files
share the same set of bindings. This avoids duplication and keeps the
board files consistent.

- Changed led node names
- Added color/function/function-enumerator properties
