iio: accel: mma7455_i2c: Convert to i2c's .probe_new()
...
.probe_new() doesn't get the i2c_device_id * parameter, so determine
that explicitly in the probe function.

i2c: Make remove callback return void
...
The value returned by an i2c driver's remove function is mostly ignored.
(Only an error message is printed if the value is non-zero that the
error is ignored.)
So change the prototype of the remove function to return no value. This
way driver authors are not tempted to assume that passing an error to
the upper layer is a good idea. All drivers are adapted accordingly.
There is no intended change of behaviour, all callbacks were prepared to
return 0 before.

iio:accel:mma7455_core: Move exports into IIO_MMA7455 namespace
...
In order to avoid unnecessary pollution of the global symbol namespace
move the core mma7455 functions into an mma7455 specific namespace and
import that into the two bus modules.

iio: accel: mma7455: Make mma7455_core_remove() return void
...
Up to now mma7455_core_remove() returns zero unconditionally. Make it
return void instead which makes it easier to see in the callers that
there is no error to handle.
Also the return value of i2c and spi remove callbacks is ignored anyway.

iio: accel: mma7455_i2c: Add OF device ID table
...
The driver doesn't have a struct of_device_id table but supported devices
are registered via Device Trees. This is working on the assumption that a
I2C device registered via OF will always match a legacy I2C device ID and
that the MODALIAS reported will always be of the form i2c:<device>.
But this could change in the future so the correct approach is to have an
OF device ID table if the devices are registered via OF.

Add support for Freescale MMA7455L/MMA7456L 3-axis in 10-bit mode for
I2C and SPI bus. This rather simple driver that currently doesn't
support all the hardware features of MMA7455L/MMA7456L.
Tested on Embedded Artist's LPC4357 Dev Kit with MMA7455L on I2C bus.
