[PATCH 3/4] Input: silead_gsl1680: Allow silead_ts_read_props to override default resolution

[Hans de Goede <hdegoede@redhat.com>]

Set the default max_x / max_y in prop.max_? before calling
silead_ts_read_props, so that silead_ts_read_props can override
them. This will be used to fill in DMI based touchscreen info on
ACPI based tablets, since the APCI touchscreen node does not
contain resolution info.
