Subject: [PATCH 4/5] PM / devfreq: make event/exynos-nocp explicitly non-modular

The Kconfig currently controlling compilation of this code is:

event/Kconfig:config DEVFREQ_EVENT_EXYNOS_NOCP
event/Kconfig:  bool "EXYNOS NoC (Network On Chip) Probe DEVFREQ event Driver"

...meaning that it currently is not being built as a module by anyone.

Lets remove the modular code that is essentially orphaned, so that
when reading the driver there is no doubt it is builtin-only.

We explicitly disallow a driver unbind, since that doesn't have a
sensible use case anyway, and it allows us to drop the ".remove"
code for non-modular drivers.

Since module_platform_driver() uses the same init level priority as
builtin_platform_driver() the init ordering remains unchanged with
this commit.

We also delete the MODULE_LICENSE tag etc. since all that information
is already contained at the top of the file in the comments.
