[PATCH 5.4 45/60] iio: adc: axp288: Override TS pin bias current for some models

[Greg Kroah-Hartman <gregkh@linuxfoundation.org>]

From: Hans de Goede <hdegoede@redhat.com>

commit 048058399f19d43cf21de9f5d36cd8144337d004 upstream.

Since commit 9bcf15f75cac ("iio: adc: axp288: Fix TS-pin handling") we
preserve the bias current set by the firmware at boot. This fixes issues
we were seeing on various models.

Some models like the Nuvision Solo 10 Draw tablet actually need the
old hardcoded 80ųA bias current for battery temperature monitoring
to work properly.

Add a quirk entry for the Nuvision Solo 10 Draw to the DMI quirk table
to restore setting the bias current to 80ųA on this model.
