Subject[PATCH 18/18] mfd: wm8400-core: Make it explicitly non-modular
Date
The Kconfig currently controlling compilation of this code is:

drivers/mfd/Kconfig:config MFD_WM8400
drivers/mfd/Kconfig: bool "Wolfson Microelectronics WM8400"

...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_init was not in use by this code, the init ordering
remains unchanged with this commit.

A trivial function rename from wm8400_module_init to the name
wm8400_driver_init is also done to reduce possible confusion.

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.
