glados: Enable wake-on-wifi
- Assign GPE DW0 to GPP_B block
- Enable GPP_B16 as ACPI_SCI for wake
- Define PCIe WLAN device in ACPI with GPE0_DW0_16 for _PRW
Note that current designs cannot wake from Deep S3 via wifi.
BUG=chrome-os-partner:40635
BRANCH=none
TEST=tested on glados:
1-disable deep s3 in devicetree.cb
2-enable magic packet with "iw phy phy0 wowlan enable magic-packet"
3-powerd_dbus_suspend to go to S3
4-wake system with magic packet
