[PATCH v2 06/32] ASoC: rt5651: Configure jack-detect source through a device-property

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

Configure the jack-detect source through a device-property which can be
set by code outside of the codec driver. Rather then putting platform
specific DMI quirks inside the generic codec driver.

And move the jack-detect-source quirk for the KIANO SlimNote 14.2, which
was present inside the codec driver to the machine driver, where we can
bundle it together with the other quirks already present for this laptop.
