mb/google/cyan: Adjust ACPI interrupt triggering for audio codecs
The jack detect GPIOs are initialized as dual edge-triggered GPIs,
and Linux doesn't care if they are set to ActiveLow, ActiveHigh, or
ActiveBoth -- a single interrupt is detected on jack insertion or
removal.
The Windows drivers on the other hand, will not function unless the
codec and LPE ACPI interrupts entries are set as in the Intel
Cherry Trail Tianocore platform reference code.
So adjust the ACPI interrupt triggers to make Windows happy, since
Linux doesn't care either way.
Test: boot Linux (GalliumOS 3.1) and Windows 10 on google/edgar,
observe functional audio output for both built-in speakers and
headphones.
