Subject: [PATCH 5.12 134/173] hwmon: (tps23861) define regmap max register

From: Robert Marko <robert.marko@...tura.hr>

commit fb8543fb863e89baa433b4d716d73395caa1b7f4 upstream.

Define the max register address the device supports.
This allows reading the whole register space via
regmap debugfs, without it only register 0x0 is visible.

This was forgotten in the original driver commit.
