OpenSBI: Fixed ecall return
Helps to actually return the right values...

Ecall was returning the passed arguments a0 and a1 instead of the actual
return values from the registers(r_a0 and r_a1)

Shit explanation just read the diff, its one line

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

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
