KVM: MIPS: Convert get/set_regs -> vcpu_load/put

Convert the get_regs() and set_regs() callbacks to vcpu_load() and
vcpu_put(), which provide a cpu argument and more closely match the
kvm_arch_vcpu_load() / kvm_arch_vcpu_put() that they are called by.

This is in preparation for moving ASID management into the
implementations.
