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.
