The Arm Ltd board bindings are a bit unusual in that they define child nodes for various syscon's. The schemas are also incomplete as they lack constraints on having additional properties and some properties are missing. As the bindings for the different platforms only vary by compatibles, combine them into a single schema doc. Add the "arm,im-pd1-syscon" compatible which was not documented. Add "ranges", "#address-cells", and "#size-cells properties which were missing. With this, fix the error exposed in the register-bit-led binding.

The ARM RealView series of reference designs were built to explore the ARM
|
|
11, Cortex A-8 and Cortex A-9 CPUs. This included new features compared to
|
|
the earlier CPUs such as TrustZone and multicore (MPCore).
