[PATCH 06/10] platform/chrome: cros_ec_typec: Move structs to header

From: Prashant Malani
Date: Tue Dec 27 2022 - 20:06:52 EST


Move ChromeOS Type-C structs into their own header, so they can be
referenced by other files which can be added to the same module.

No functional changes introduced by this patch.
