[PATCH 3/4] mfd: da9055-core: make it explicitly non-modular

[Paul Gortmaker]

The Kconfig currently controlling compilation of this code is:

drivers/mfd/Kconfig:config MFD_DA9055
drivers/mfd/Kconfig:    bool "Dialog Semiconductor DA9055 PMIC Support"

...meaning that it is never being built as a module.

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

The exit function deleted here wasn't even registered with module_exit,
so it truly was dead 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.

We replace module.h with init.h and export.h ; the latter since the
file does export some symbols
