[PATCH 2/2] ASoC: Intel: bytcr_rt5640: Add new swapped-speakers quirk

[Hans de Goede <hdegoede@redhat.com>]

Some BYTCR x86 tablets with a rt5640 codec have the left and right channels
of their speakers swapped.

Add a new BYT_RT5640_SWAPPED_SPEAKERS quirk for this which sets
cfg-spk:swapped in the components string to let userspace know
about the swapping so that the UCM profile can configure the mixer
to correct this.

Enable this new quirk on the Medion Lifetab S10346 which has its
speakers swapped.
