ec/google/chromeec: Update google_chromeec_usb_pd_control() 

Add parameter `active_cable` to obtain the cable type
(active or passive) which is needed for USB-C configuration for
some SoCs (at least Intel TGL and ADL), change the function name to
google_chromeec_usb_pd_get_info() for better understanding.
