Bibo Mao ec943318bc LoongArch: Add steal time support in guest side 
Upstream: no

Percpu struct kvm_steal_time is added here, its size is 64 bytes and
also defined as 64 bytes, so that the whole structure is in one physical
page.

When vcpu is onlined, function pv_register_steal_time() is called. This
function will pass physical address of struct kvm_steal_time and tells
hypervisor to enable steal time. When vcpu is offline, physical address
is set as 0 and tells hypervisor to disable steal time.
