Revert "usb: typec: mux: avoid duplicated mux switches"

Browse source

This reverts commit b145c3f29d.

The deduplication logic appears to cause issues with separate
SBU muxes. The mode-switch call on these (like gpio-sbu-mux)
never appeared, so no successful mode-switch happened. The more
high-end Parade PS883X redrivers are not affected due to being
retimer-switch. The revert fixes dp altmode mode-switch for both.

Tested on:
  Lenovo Thinkbook 16 G7 QOY
  Lenovo Ideapad 5 2in1 14Q8X9
  Microsoft Windows Dev Kit 2023 (Blackrock)
  Lenovo Thinkpad T14s G6
