Input: i8042 - add ByteSpeed touchpad to noloop table

commit a48491c65b513e5cdc3e7a886a4db915f848a5f5 upstream.

It looks like the C15B laptop got another vendor: ByteSpeed LLC.

Avoid AUX loopback on this touchpad as well, thus input subsystem will
be able to recognize a Synaptics touchpad in the AUX port.
