Mode in struct typec_altmode is used to indicate the index of the
altmode on a port, partner or plug. It is used in enter mode VDMs but
doesn't make much sense for matching against altmode drivers or for
matching partner to port altmodes.

Changes in v5:
- Rebase with module_alias_printf

Changes in v3:
- Removed mode from altmode device ids
- Updated modalias for typecd bus to remove mode
- Re-ordered to start of series

Changes in v2:
- Update altmode_match to ignore mode entirely
- Also apply the same behavior to typec_match
