[PATCH v2 0/7] RISC-V: KVM: Add Svadu/Zicfiss/Zicfilp FWFT support

This patchset based on the patchset "RISC-V: KVM: Add Zicfiss/Zicfilp
support".

The patch includes all the function of original patchset from Quan:
adding the Svadu/Zicfiss/Zicfilp FWFT for the RISC-V KVM. And this
patchset already passes the KVM unit test.

Changed from Quan's v1:
- https://lore.kernel.org/kvm/[email protected]/
1. rebase to the latest master.
2. Split Svadu change as separate patch
3. Fix all build error from the original series
4. Remove the Svadu check in kvm_riscv_vcpu_config_ran_once() and in
   favor of the FWFT.
5. Remove the LPE/SSE setting bit in kvm_riscv_vcpu_config_ran_once()
   (kvm_riscv_vcpu_setup_config() in original patchset)
