Upload tiny kernel build config for RVVM

- Tiny statically linked kernel with no modules needed to function
- Supports all RVVM devices and virtio, so it may also boot on QEMU
- Features fbdev driver for the framebuffer, which is smaller and sometimes faster, but doesn't work with Wayland
- Uses linux-shrink patch to make the kernel smaller

How to build:
patch -p1 -i linux-shrink.patch (Optional)
mv config_tiny_6.2 .config
make ARCH=riscv CROSS_COMPILE=riscv64-linux-gnu- -j$(nproc)
