Subject: [PATCH 0/3] platform/chrome: cros_ec_typec: Add plug and plug altmodes

This patch series add plug registration support to the cros-ec-typec
driver. It also adds support for registering alternate modes for the
registered plug. These features utilize the API provided by the Type C
connector class framework.

The first patch adds support to the connector class framework for the
number_of_alternate_modes attribute (along with the relevant ABI
documentation).

The next two patches add plug registration, and then altmode
registration for the plugs. The latter of these two patches utilizes the
new function for plug number_of_alternate_modes introduced in the first patch.

This series is based on top of the following branch and other patch
series (applied in the order specified):
- Branch: chrome-platform for-next [1], which is currently set to the
  "Linux 5.10-rc1" tag.
- cros-ec-typec: Patch series to register PD identity information + partner altmodes[2]
- cros-ec-typec: Patch series to register cable[3]
- cros-ec-typec: Patch series to add partner number_of_altmodes[4]
