Paul Gortmaker 58f388bcf0 memory: samsung: exynos-srom: make it explicitly non-modular
The Kconfig currently controlling compilation of this code is:

memory/samsung/Kconfig:config EXYNOS_SROM
memory/samsung/Kconfig: bool "Exynos SROM controller driver" if COMPILE_TEST

...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.

Also note that MODULE_DEVICE_TABLE is a no-op for non-modular code.

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

Pavel Fedin 8ac2266d88 memory: samsung: exynos-srom: Add support for bank configuration
Implement handling properties in subnodes and adding child devices to the
system. Child devices will not be added if configuration fails.

Since the driver now does more than suspend-resume support, dependency on
CONFIG_PM is removed.
