From d1bfc3dfb848ea1b402e2299b1e3b974aad9be60 Mon Sep 17 00:00:00 2001

Subject: [backport 1/2] mlxsw: core: thermal: Set default thermal trips at
initialization

Set default thermal trip temperatures during thermal zone
initialization. Otherwise polling time for thermal control
could stay zero and such thermal zones will not be triggered by
thermal algorithm.
