thermal: exynos: Defer probe if vtmu is present but not registered
The driver doesn't check if the regulator_get_optional return value is -EPROBE_DEFER so it will wrongly assume that the regulator couldn't be found just because the regulator driver wasn't registered yet, i.e: exynos-tmu 10060000.tmu: Regulator node (vtmu) not found In this case the return value should be propagated to allow the driver probe function to be deferred until the regulator driver is registered.
