[Qemu-riscv] [PATCH] tests/boot_linux_console: add a test for riscv64 + virt

[Chih-Min Chao]

Similar to the mips + malta test, it boots a Linux kernel on a virt
board and verify the serial is working.  Also, it relies on the serial
device set by the machine itself.

If riscv64 is a target being built, "make check-acceptance" will
automatically include this test by the use of the "arch:riscv64" tags.

Alternatively, this test can be run using:

  $ avocado run -t arch:riscv64 tests/acceptance
