Paul Gortmaker ed4dba99ca reset: berlin: make it explicitly non-modular
The Kconfig currently controlling compilation of this code is:

drivers/reset/Kconfig:config RESET_BERLIN
drivers/reset/Kconfig:  bool "Berlin Reset Driver" if COMPILE_TEST
drivers/reset/Kconfig:  default ARCH_BERLIN

or

arch/arm/mach-berlin/Kconfig:menuconfig ARCH_BERLIN
arch/arm/mach-berlin/Kconfig:   bool "Marvell Berlin SoCs" if ARCH_MULTI_V7

or

arch/arm64/Kconfig.platforms:config ARCH_BERLIN
arch/arm64/Kconfig.platforms:   bool "Marvell Berlin SoC Family"

...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.

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
was (or is now) contained at the top of the file in the comments.

The berlin_reset_ops structure is never modified. Make it const.

Philipp Zabel 27ca5aaa36 reset: berlin: drop DT cell size check
Now that the DT cell size check has been moved to the core,
there is no need to check again.

Masahiro Yamada d1f15aa095 reset: check return value of reset_controller_register()
Currently, reset_controller_register() always return 0, but it would
be better to check its return code.

Antoine Tenart bfff629618 reset: berlin: drop arch_initcall initialization
With proper platform driver probing for berlin reset driver, drop the
arch_initcall workaround.

Antoine Tenart aed6f3cadc reset: berlin: convert to a platform driver
The Berlin reset controller was introduced without being a platform
driver because of a needed DT rework: the node describing the reset
controller also describes the pinctrl and clk controllers...

Prepare conversion by adding a platform driver probe to a new
compatible "marvell,berlin2-reset" with syscon regmap.
