KVM: Documentation: Add info regarding KVM_ARM_VCPU_PSCI_0_2 feature

Browse source 
We have in-kernel emulation of PSCI v0.2 in KVM ARM/ARM64. To provide
PSCI v0.2 interface to VCPUs, we have to enable KVM_ARM_VCPU_PSCI_0_2
feature when doing KVM_ARM_VCPU_INIT ioctl.

The patch updates documentation of KVM_ARM_VCPU_INIT ioctl to provide
info regarding KVM_ARM_VCPU_PSCI_0_2 feature.
