The RISC-V arch_timer selftests is used to validate Sstc timer
functionality in a guest, which sets up periodic timer interrupts
and check the basic interrupt status upon its receipt.
This KVM selftests was ported from aarch64 arch_timer and tested
with Linux v6.7-rc8 on a Qemu riscv64 virt machine.
---
Changed since v4:
* Rebased to Linux 6.7-rc8
* Added new patch(2/12) to clean up the data type in struct test_args
* Re-ordered patch(11/11) in v4 to patch(3/12)
* Changed the timer_err_margin_us type from int to uint32_t
