[PATCH 2/5] Input: synaptics - Log queried and quirked dimension values

[Daniel Martin <daniel.martin@secunet.com>]

From: Daniel Martin <consume.noise@gmail.com>

Logging the dimension values we queried (info) and the values we use
from a quirk to overwrite (warn) can be helpful for debugging.

This partly relates to bug:
