Thermal core tries to read temperature during sensor registering in
thermal_zone_of_sensor_register(). In that time Exynos TMU driver and
hardware are not yet initialized. Commit 0eb875d88aaa ("thermal:
exynos: Reading temperature makes sense only when TMU is turned on")
added a boolean flag to prevent reading bogus temperature in such
case but it exposed warning message during boot:
[ 3.864913] thermal thermal_zone0: failed to read out thermal zone (-22)
Return EAGAIN in such case to skip omitting such message because it
might mislead user.
