OpenSBI: Added base extension
General notes:

For now im just going to leave all the responses as SbiRet but once I
decide how I want to handle returning errors I would like to return more
useful values.

In the cpp file I define a enum class "ExtensionId" with only one
member. For now the thought is that its descriptive and is consistent
with how the legacy extension is written. I'll also do the same thing
with FunctionId in the legacy extension after this commit for
consistency.

Formatting
It would be nice if I would stay consistent with namespace formatting

Maybe I should use a real linter or something...

OpenSBI memes
Added legacy extension

Fixed typing memes by just define a sbiword_t typedef

Renamed sbiret_t to SbiRet, I think i'll only use _t for typedefs

Added ecall() variant that takes no additional arguments

Moved opensbi includes to includes/opensbi/...

kernel.cpp uses the legacy extensions instead of raw ecalls

All legacy extension calls are marked as deprecated

Drivers: Started OpenSBI driver
Just ecall wrapper for now

TODO: Build system changes are lazy and need to be figured out

TODO: Looks like kernel.cpp was indented with tabs, fix
