thermal: of-thermal: Fix setting of set_emul_temp hook 

Currently thermal zone set_emul_temp is set unconditionally
with of_thermal_set_emul_temp function. Set this only if the
set_emul_temp hook is provided for thermal_zone_of_device_ops.

This fixes emul_temp failures on platforms for which set_emul_temp
hook is not populated.

Fixes: "184a4bf623f (thermal: of: Extend current
	of-thermal.c code to allow setting emulated temp)"
