meta-facebook: santabarbara: update SWB EID removal for AEB SWB

mctp_remove only cleared the EID on i2c-114 (BRCM SWB). The AEB SWB has
four boards on i2c-114..117, so stale EIDs remained after DC off. Loop
over i2c-114..117; buses with no SWB are skipped, so BRCM SWB is
unchanged.

Tested-on santabarbara:
