The chip data of HDMI LPE audio is set to drm_i915_private which is not
consistent with the expectation by x86 APIC driver. In the case of not
enabling CONFIG_CPUMASK_OFFSTACK, this would cause kernel panic while doing
CPU hotplug. Since the dependency of IRQ chip data was removed from HDMI
LPE audio by Commit 9bd9590997b92fbd79fd028f704f6c584b4439d7 ("drm/i915:
Stop pretending to mask/unmask LPE audio interrupts"), remove the
code of setting IRQ chip data to resolve this issue.
