[PATCH v3 04/11] platform/chrome: cros_ec_typec: Make disc_done flag partner-only

From: Prashant Malani
Date: Mon Nov 16 2020 - 15:13:34 EST


Change the disc_done flag, which indicates whether PD discovery is
complete, to sop_disc_done instead, since we will process SOP and SOP'
discovery data separately.
