[X/B/F/G/H/Unstable][SRU][PATCH 1/1] Input: i8042 - add ByteSpeed touchpad to noloop table

[Po-Hsu Lin]

BugLink: https://bugs.launchpad.net/bugs/1906128

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.
