riscv: add support for OpenSBI
Call OpenSBI in M-Mode and use it to set up SBI and to lockdown the
platform. It will also jump to the specified payload when done.
This behaviour is similar to BL31 on aarch31.
The payload is 41KiB in size on qemu.
Tested on qemu-riscv:
Required to boot a kernel as OpenSBI's instruction emulation feature
is required on that virtual machine.
Tested on SiFive/unleashed:
The earlycon is working. No console after regular serial driver
should take over, which might be related to kernel config.
