[PATCH v9 4/5] tests/functional/riscv64: add riscv-server-ref tests

[Daniel Henrique Barboza <daniel.barboza@oss.qualcomm.com>]

Add tests for the recently added riscv-server-ref machine:

- a new test_opensbi.py test.  The idea is to have a quick test that can
catch trivial regressions that would prevent OpenSBI to finish;
- a new Linux boot "thorough" test that will boot the machine up to the
buildroot prompt.
- a TPM specific selftest for the riscv-server-ref board.  The test
will be skipped if there's no 'swtpm' in the host.
