mb/lenovo/x220: disable ME
The ME hangs, the lspci shows no memory and the linux kernel
tries to request irq 0 twice. After suspend-resume the linux
kernel warns about double used irq.
genirq: Flags mismatch irq 0. 00000080 (mei_me) vs. 00015a00 (timer)
mei_me 0000:00:16.0: request_threaded_irq failed: irq = 0.
dpm_run_callback(): pci_pm_resume+0x0/0xa0 returns -16
PM: Device 0000:00:16.0 failed to resume async: error -16
