RISC-V: KVM: Replace aia_set_hvictl() with aia_hvictl_value()
The aia_set_hvictl() internally writes the HVICTL CSR which makes
it difficult to optimize the CSR write using SBI NACL extension for
kvm_riscv_vcpu_aia_update_hvip() function so replace aia_set_hvictl()
with new aia_hvictl_value() which only computes the HVICTL value.
