tests/acpi: Add expected ACPI AML files for RISC-V

As per the step 5 in the process documented in bios-tables-test.c,
generate the expected ACPI AML data files for RISC-V using the
rebuild-expected-aml.sh script and update the
bios-tables-test-allowed-diff.h.

These are all new files being added for the first time. Hence, iASL diff
output is not added.
