This adds openSBI support. openSBI aims to be the reference
implementation for the M mode firmware. We are going to use it to remove
BBL from the boot flow.
The eventual aim is to have openSBI merged into the meta layer to
support qemuriscv* machines.
Unfortunately openSBI requires a 5.0 kernel, so at the moment we aren't
going to use it.

We are sort of hijacking OE-Core recipe here, so lets be careful and
make it such that it only happens for risv64, which makes a multi-BSP
scenario work again.
This repo seems to be rebasing :( so add rebaseable=1 so bitbake knows
about it
update to latest rev as of today
