[PATCH] ALSA: hda: improve bass speaker support for ASUS Zenbook UM5606WA

[Jaroslav Kysela <perex@xxxxxxxx>]

This hardware has ALC294 codec with speaker NID 0x17 and bass speaker
NID 0x15.

This patch removes DAC NID 0x06 (without volume control) from
the connection list for bass speaker NID 0x15. Both speaker PINs
are routed to DAC NID 0x03 with this change.
