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

Build System: More better
Split code into generic, arch, and platform

Made QEMU its own platform

Added shitty uart upload script for lichee board until I can get fel to
actually upload uboot payloads without hanging

TODO: Move platform selection out of build script

TODO: Move arch specific stuff from kernel to arch

TODO: Common linker script for arch instead of having a copy in each
platform

Initial Commit
Mostly stolen from https://github.com/avdgrinten/riscv-toy-os

Changed load address to 0x45000000 so it would run on real hardware

Played around with GPIO and the watchdog
