mb/google/hatch: Enable PCIe WLAN and BT
Enable PCIe WLAN for hatch
1. Enable PCI port 14 for PCIe WLAN
2. Enable CLKREQ, CLK SRC 3 for PCI port 14
3. GPIO pad config for WLAN and BT
USB port for BT has already been enabled so not included in this patch
BUG=b:120914069
BRANCH=none
TEST=check if code compiles correctly and verify GPIO configuration with
schematics
