KVM: x86: PIT: Preserve state of speaker port data bit
Currently the state of the speaker port (0x61) data bit (bit 1) is not saved in the exported state (kvm_pit_state2) and hence is lost when re-constructing guest state. This patch removes the 'speaker_data_port' field from kvm_kpit_state and instead tracks the state using a new KVM_PIT_FLAGS_SPEAKER_DATA_ON flag defined in the API.
