Move from i2c_new_dummy() to i2c_new_dummy_device(), so we now get an
ERRPTR which we use in error handling.

Add const to bin_attribute structures as they are only passed to the
functions sysfs_{remove/create}_bin_file. The arguments passed are of
type const, so declare the structures to be const.
Done using Coccinelle.

Pull i2c updates from Wolfram Sang:
"Features:
- new drivers: Renesas EMEV2, register based MUX, NXP LPC2xxx
- core: scans DT and assigns wakeup interrupts. no driver changes needed.
- core: some refcouting issues fixed and better API for that
- core: new helper function for best effort block read emulation
- slave framework: proper DT bindings and userspace instantiation
- some bigger work for xiic, pxa, omap drivers
.. and quite a number of smaller driver fixes, cleanups, improvements"

The I2C core always reports the MODALIAS uevent as "i2c:<client name>"
regardless if the driver later is match using the I2C id_table or the
of_match_table. So the driver needs to export the I2C table and this
be built into the module or udev won't have the necessary information
to auto load the correct module when the device is added.

The change removes redundant sysfs binary file boundary check, since
this task is already done on caller side in fs/sysfs/file.c

None of these files are actually using any __init type directives
and hence don't need to include <linux/init.h>. Most are just a
left over from __devinit and __cpuinit removal, or simply due to
code getting copied from one driver to the next.

This patch converts the drivers in drivers/misc/* to use the
module_i2c_driver() macro which makes the code smaller and a bit
simpler.

There is no point in implementing a detect callback for the MAX6875, as
this device can't be detected. It was there solely to handle "force"
module parameters to instantiate devices, but now we have a better sysfs
interface that can do the same.
So we can get rid of the ugly module parameters and the detect callback.
This basically divides the binary module size by 2.

This driver only reads the user EEPROM of that chip, so we can move it
to the eeprom-directory in order to further clean up (and later remove)
drivers/i2c/chips.
The Kconfig text was updated to match the current functionality,
dropping the meanwhile obsoleted parts.
Defconfigs have been adapted.
