serial: 8250_of: Drop quirk fot NPCM from 8250_port

[ Upstream commit cd0eb354d441488feed6685adbeb1acd45db1b8d ]

We are not supposed to spread quirks in 8250_port module especially
when we have a separate driver for the hardware in question.

Move quirk from generic module to the driver that uses it.
