soc/intel/cannonlake: Add support to log XHCI wake events
Enhance elog wake source information with more details about which USB port
resulted in a wake from S3 or S0ix.
BUG=b:123429132
BRANCH=none
TEST=``FW_NAME=hatch emerge-hatch chromeos-ec depthcharge vboot_reference
libpayload coreboot-private-files intel-cmlfsp coreboot-private-files-hatch
coreboot chromeos-bootimage``
Ensure /build/hatch/firmware/image-hatch.serial.bin has been built.
Plug a keyboard into a USB port on the DUT.
Switch the DUT to the console (Ctrl-Alt-F2, or use the AP console via
servo).
On the console, run ``powerd_dbus_suspend``.
Wait for the DUT to enter low power mode.
Verify low power mode by issuing the ``powerinfo`` command on the EC
console (via servo). Expect to see ``power state 4 = S0ix``.
Press a key on the USB keyboard.
The DUT wakes up.
On the console, run ``mosys eventlog list`` and look for the wake source.

159 | 2019-06-26 12:14:05 | Wake Source | GPE # | 109
Program image-hatch.serial.bin into the DUT using flashrom.
Repeat the ``powerd_dbus_suspend``, ``powerinfo``, ``mosys eventlog list``
sequence.
