ramoops: use pstore interface
Instead of using /dev/mem directly and forcing userspace to know (or extract) where the platform has defined persistent memory, how many slots it has, the sizes, etc, use the common pstore infrastructure to handle Oops gathering and extraction. This presents a much easier to use filesystem-based view to the memory region. This also means that any other tools that are written to understand pstore will automatically be able to process ramoops too.
