[PATCH v2] extcon: max77843: convert to module_platform_driver()

[Brian Masney]

This driver is currently registered at the subsys_initcall level,
however this driver shouldn't be needed for early boot, and can be
converted to use the standard module_init().

This driver already has the standard MODULE_DEVICE_TABLE(), is
configured in the Kconfig to be a tristate, and the driver doesn't
have suppress_bind_attrs set, so let's go ahead and reduce boilerplate
code in this driver and convert it over to use the macro
module_platform_driver().

Note that currently there is no __exit function defined and this change
will add an __exit function that unregisters the platform driver.
