Subject: Input: synaptics - split synaptics_resolution(), query first

From: Daniel Martin <consume.noise@xxxxxxxxx>

commit 8b04baba10b007f8b6c245a50be73cf09cc3a414 upstream.

Split the function synaptics_resolution() into synaptics_resolution() and
synaptics_quirks().  synaptics_resolution() will be called before
synaptics_quirks() to query dimensions and resolutions before overwriting
them with quirks.
