[PATCH] ASoC: rt5645: Add jack detection workaround for MINIX Z83-4 based devices

[Ian W MORRISON <ianwmorrison@gmail.com>]

The MINIX NEO Z83-4 and MINIX NEO Z83-4 Pro devices requires jd_mode=3
to make the jack detection work. Using a BIOS DMI product of "Z83-4"
will match both devices of 'NEO Z83-4' and 'Z83-4 Pro'.
