ALSA: hda: intel: Add Lenovo IdeaPad Z570 to probe denylist
Lenovo IdeaPad Z570 with NVIDIA GeForce Ge 540M doesn't have sound on the discrete GPU. The HDA controller in DGPU is disabled by BIOS, but then reenabled by quirk_nvidia_hda(). The probe fails and ends up with the "GPU sound probed, but not operational" error. Add this laptop to DMI-based denylist to prevent probe early. DMI is used, because the audio device has zero subsystem IDs, and this entry would be too much, blocking all 540M chips: PCI_DEVICE_SUB(0x10de, 0x0bea, 0x0000, 0x0000) Also, this laptop comes in a variety of modifications with different NVIDIA GPUs, so the DMI check will cover them all.
