A platform_driver does not need to set an owner, it will be populated by the
driver core.

This won't be used by NAND subsystem as we implement cmdfunc on our
own, but will allow us to write a bit cleaner code.

We are supposed to mask value, not multiply it. Add some comments btw.

Pull MTD update from David Woodhouse:
"Fairly unexciting MTD merge for 3.9:
- misc clean-ups in the MTD command-line partitioning parser
(cmdlinepart)
- add flash locking support for STmicro chips serial flash chips, as
well as for CFI command set 2 chips.
- new driver for the ELM error correction HW module found in various
TI chips, enable the OMAP NAND driver to use the ELM HW error
correction
- added number of new serial flash IDs
- various fixes and improvements in the gpmi NAND driver
- bcm47xx NAND driver improvements
- make the mtdpart module actually removable"

When platform_driver_probe() is used and no device is registered for
this driver -ENODEV is returned and and error message is shown. Not all
BCM47xx SoC have a nand flash chip controller and chip and for them an
error message was shown.

CONFIG_HOTPLUG is going away as an option. As a result, the __dev*
markings need to be removed.
This change removes the use of __devinit, __devexit_p, and __devexit
from these drivers.
Based on patches originally written by Bill Pemberton, but redone by me
in order to handle some of the coding style issues better, by hand.

Recently imlemented writing support has shown that current num of
retries is too low. Writing requires longer waiting than simple reading.

BCMA bus can contain NAND flash memory, it's registered in system as
platform device. This adds required hooks and place for controler
specific drivers.
