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 v6.6-rc1 on a Qemu riscv64 virt machine.
---
Changed since v2:
* Rebase to Linux 6.6-rc1
* Add separate patch for kvm/Makefile improvement
* Move aarch64 specific macros to aarch64/arch_timer.c
* Add -DCONFIG_64BIT to kvm/Makefile CFLAGS to ensure
only 64bit registers were available in csr.h
* Avoid some #ifdef in kvm/arch_timer.c by setting some
aarch64 specific variable to 0 on risc-v
