drm/amd: Skip smu_v13 register irq on SRIOV VF
[Why]
VF do not need to handle SMU IRQ state.
L1 Policy will block VF access THM_THERMAL_INT_CTRL and MP1_SMN_IH_SW_INT/CNTL.
[How]
Skip smu_v13 init register_irq_handler under SRIOV VF.
And add irq_src check in enable/disable thermal alert
to avoid thermal alert enable/disable fail.
