driver/tcpm/nct38xx: Remove write to RO register
`TCPC_REG_DEV_CAP_2` is a RO register according to the TCPC spec and the
NCT38xx datasheet. Writes to this register have no effect on real
hardware. The vendor has also confirmed that they are not aware of any
workarounds that would explain this write. Remove it.
