[PATCH 2/2] mfd: cros_ec: Instantiate the CrOS USB PD logger driver

[Enric Balletbo i Serra]

Add the cros-usbpd-logger driver for logging event data for the USB PD
charger available in the Embedded Controller on ChromeOS systems. The
logging feature is logically separate functionality from charge manager,
hence is instantiated as a different driver.

Lee, this is send as separate patch because touches the MFD subsystem,
apart from that the driver won't be instantiated if [1/2] is not
merged, which I think is not a problem, it is safe for both go through
their subsystem separately.

Thanks,
 Enric
