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.

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.

The Exynos TMU DT binding says that the vtmu-supply is optional but the
driver uses devm_regulator_get() that creates a dummy regulator if it's
not defined in the DT. For example the following message is in the log:
10060000.tmu supply vtmu not found, using dummy regulator
Use the optional version of regulator_get() that doesn't create a dummy
regulator and instead returns a -ENODEV errno code. Since it's expected
that a regulator may not be defined and the driver will inform about it:
exynos-tmu 10060000.tmu: Regulator node (vtmu) not found

When DeviveTree contains more trip-points than SoC can configure
(usually more than four) and polling mode is not enabled, then the
remaining trip-points will be silently ignored. No interrupts will be
generated for them.
This might be quite dangerous when one provides DTB with a
non-configurable critical trip-point, like (assuming four supported
thresholds in TMU):
- alert @50 C (type: active),
- alert @60 C (type: active),
- alert @70 C (type: active),
- alert @80 C (type: active),
- critical @120 C (type: critical) <- no interrupts generated.
This is a mistake in DTB so print a message in such case.
