Subject: [PATCH] thermal: max77620: Remove duplicate error message

From: Thierry Reding <treding@...dia.com>

The thermal_of_zone_register() function already prints an error message
when appropriate, so remove the extra one from the MAX77620 thermal
driver.

This fixes a spurious error message when no thermal zone was defined
for the MAX77620 in device tree.
