Subject: [PATCH] thermal: mtk_thermal: remove redundant initializations of several variables

From: Colin Ian King <colin.king@...onical.com>

Several variables are being initialized with values that is never
read and being updated later with a new value. The initializations
are redundant and can be removed.

Addresses-Coverity: ("Unused value")
