From 55fc280e951ab2b39f3dcb640edc1b1eebc6d173 Mon Sep 17 00:00:00 2001

Subject: Input: tsc2007 - read "ti,poll-period" as u32

The "ti,poll-period" property is documented as a normal uint32 cell.
The driver used a u64 helper, which makes the helper type disagree with
the schema even though the stored value is still small.

Read "ti,poll-period" with the u32 helper matching the documented DT
cell size.
