Subject[PATCH 02/18] mfd: adp5520: Make it explicitly non-modular
Date
The Makefile/Kconfig currently controlling compilation of this code is:

drivers/mfd/Makefile:obj-$(CONFIG_PMIC_ADP5520) += adp5520.o
drivers/mfd/Kconfig:config PMIC_ADP5520
drivers/mfd/Kconfig: bool "Analog Devices ADP5520/01 MFD PMIC Core Support"

...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.

We explicitly disallow a driver unbind, since that doesn't have a
sensible use case anyway, and it allows us to drop the ".remove"
code for non-modular drivers.

Since module_i2c_driver() uses the same init level priority as
builtin_i2c_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.
