mmc: sdhci-pci: Quirk for broken command queuing on Intel GLK-based Positivo models

commit 50c78f398e92fafa1cbba3469c95fe04b2e4206d upstream.

Disable command queuing on Intel GLK-based Positivo models.

Without this quirk, CQE (Command Queuing Engine) causes instability
or I/O errors during operation. Disabling it ensures stable
operation on affected devices.
