This driver makes no use of linux/regulator/driver.h which should only
be used by drivers implementing a regulator.  Since it's unlikely to
ever need anything from there remove the include.

All configurations are lost and the registers will have
default values when the hardware is suspended and resumed,
so saving the private register space context on suspend, and
restoring it on resume.

Since this commit:

commit b9a8a271 ("mfd: make mfd_remove_devices() iterate in reverse
order")

The order in which the MFD children remove has been reversed, as our
driver contains some dependencies between the devices we need to make
some changes to ensure the driver unloads cleanly.

The driver's init and exit function don't do anything besides adding and
deleting the I2C driver so the module_i2c_driver() macro could be used.

Currently is not being used because the driver is initialized at subsys
initcall level, claiming that this is done to allow consumers devices to
use the resources provided by this driver. But dependencies are in DT so
manual ordering of init calls is not necessary any more.

Add resource managed API devm_mfd_add_devices() for the mfd_add_devices().

This helps in reducing code in error path as it is not required
to call mfd_remove_devices() explicitly to remove all child-devices.
In some cases, it also helps not to implement .remove() callback
which get called during driver unbind.
