[kvm-unit-tests PATCH v2 0/3] riscv: sbi: Add support to test timer extension

[James Raphael Tiovalen <jamestiotio@gmail.com>]

This patch series adds support for testing the timer extension as
defined in the RISC-V SBI specification. The first 2 patches add
infrastructural support for handling interrupts, while the last patch
adds the actual test for the timer extension.

v2:
- Addressed all of the previous comments from Andrew.
- Updated the test to get the timer frequency value from the device tree
  and allow the test parameters to be specified in microseconds instead of
  cycles.
