mako: disable WiFi background scan

Qualcomm's WiFi driver does not implement PNO as Android expects it, which
leads to PNO commands being mishandled in the kernel, causing memory
corruption.

Disabling PNO will increase suspend power consumption by having the device wake
up every 30s for 1-2s to do a scan explicitly.  The additional cost is that of
the SoC wakingup.
