mfd: cros_ec: Check DT node for usbpd-notify add
[ Upstream commit f8db89d14efb770dd59aa0ca74386e5de68310d5 ]
Add a check to ensure there is indeed an EC device tree entry before
adding the cros-usbpd-notify device. This covers configs where both
CONFIG_ACPI and CONFIG_OF are defined, but the EC device is defined
using device tree and not in ACPI.
