Subject: [PATCH 0/4] mfd: make da90xx drivers explicitly non-modular

At the risk of repeating the same boiler plate, in this cleanup we continue
to make driver code consistent with the Makefiles/Kconfigs that control them.

This means not using modular functions/macros for drivers that can never
be built as a module.  Some of the main downfalls this leads to are:

 (1) it is easy to accidentally write unused module_exit and remove code
 (2) it can be misleading when reading the source, thinking it can be
     modular when the Makefile and/or Kconfig prohibit it
 (3) it requires the include of the module.h header file which in turn
     includes nearly everything else, thus adding to CPP overhead.
 (4) it gets copied/replicated into other drivers and thus spreads.

As always, the option exists for someone with the hardware and the desire
to extend the functionality to make any given driver tristate.  But given
the number of these tree wide and the fact that I can't test that new
extended functionality in all cases, I just make the code consistent with
existing Kconfig/Makefile settings that currently restrict them to "bool".

Build tested on linux-next for arm, arm64 and x86-64 to ensure no typos
or similar issues crept in.  The diffstat summary speaks for itself.
