mfd: max77843: Make it explicitly non-modular
The Kconfig currently controlling compilation of this code is:
drivers/mfd/Kconfig:config MFD_MAX77843
drivers/mfd/Kconfig: bool "Maxim Semiconductor MAX77843 PMIC 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.
