[PATCH alsa-ucm-conf 4/5] bytcr-rt5640: Add support for a second headphones output

[Hans de Goede]

Some devices (HP Elitepad 1000 G2) have a second headphones output
(1 on the dock, 2nd on the tablet itself) which is implemented through
the line-out output of the codec combined with an external hp-amp.

The kernel has recently gotten support for this setup and will
advertise this to userspace by adding cfg-hp2:lineout to the
components string, add support for this.
