Mode in struct typec_altmode is used to indicate the index of the
altmode on a port, partner or plug. When searching for altmodes, it
doesn't make sense to use the mode as a criteria since it could be any
value depending on the enumeration order of the driver.

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