Input: tsc2007 - read "ti,poll-period" as u32grafted

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.

+
+This program parses the output from a set of printk message lines which
+have time data prefixed because the CONFIG_PRINTK_TIME option is set, or
+the kernel command line option "time" is specified. When run with no
+options, the time information is converted to show the time delta between
+each printk line and the next.  When run with the '-b' option, all times
+are relative to a single (base) point in time.
+
+Options:
+  -h            Show this usage help.
+  -b <base>	Specify a base for time references.
+		<base> can be a number or a string.
+		If it is a string, the first message line
+		which matches (at the beginning of the
+		line) is used as the time reference.
+
+ex: $ dmesg >timefile
+    $ show_delta -b NET4 timefile
+
+will show times relative to the line in the kernel output
+starting with "NET4".
