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.
