SBI v0.2 base extension defined to allow backward compatibility and
probing of future extensions. This is also the only mandatory SBI
extension that must be implemented by SBI implementors.

With SBI v0.2, there may be more SBI extensions in future. It makes more
sense to group related extensions in separate files. Guest kernel will
choose appropriate SBI version dynamically.
Move the existing implementation to a separate file so that it can be
removed in future without much conflict.

The existing SBI specification impelementation follows v0.1
specification. The latest specification allows more scalability
and performance improvements.
Rename the existing implementation as v0.1 and provide a way
to allow future extensions.
