iio: adc: axp288: Override TS pin bias current for some models

commit 93b3b0f40109cbe68423dc9b9705eb6e5e131550 upstream.

Since commit c3fdc9ebf074 ("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.
