Clang produces the following warning

drivers/thermal/armada_thermal.c:270:33: warning: shifting a negative
signed value is undefined [-Wshift-negative-value]
1 warning        reg &= ~CONTROL1_TSEN_AVG_MASK <<
CONTROL1_TSEN_AVG_SHIFT; generated
.
               ~~~~~~~~~~~~~~~~~~~~~~~ ^

CONTROL1_TSEN_AVG_SHIFT is defined to be zero.
Since shifting by zero does nothing this variable can be removed.
