target-arm: Enable KVM_ARM_VCPU_PSCI_0_2 feature when possible
Latest linux kernel supports in-kernel emulation of PSCI v0.2 but to enable it we need to select KVM_ARM_VCPU_PSCI_0_2 feature using KVM_ARM_VCPU_INIT ioctl. Also, we can use KVM_ARM_VCPU_PSCI_0_2 feature for VCPU only when linux kernel has KVM_CAP_ARM_PSCI_0_2 capability. This patch updates kvm_arch_init_vcpu() to enable KVM_ARM_VCPU_PSCI_0_2 feature for VCPU when KVM ARM/ARM64 has KVM_CAP_ARM_PSCI_0_2 capability.
