Bug description:
SRU Justification:

[Impact]
New HP platform with Realtek ALC3315+TAS2783 audio solution fail the audio output function of the built-in speaker.


[Fix]
Backport the upstream fix: fefce60f771f ("platform/x86: serial-multi-instantiate: Add IRQ_RESOURCE_OPT for IRQ missing projects")

[Test Case]
1. Boot up the machine of new HP platforms MexusX
2. Test the speaker output function from gsd -> sound -> output -> Test on the built-in speaker
3. Click left/right speaker and make sure both channel have audio output

[Where problems could occur]
It adds missing IRQ resource for the declared SPEAKER device (TXNW2781) in ACPI table. It's only for tas2781-hda and should have no regression on other platforms w/o particular amplifier.
