onenand_release() will call mtd_device_unregister(), thus remove the redundant
mtd_device_unregister() call before onenand_release().

Replace custom invocations of parse_mtd_partitions and mtd_device_register
with common mtd_device_parse_register call. This would bring: standard
handling of all errors, fallback to default partitions, etc.

Since 'cmdline, NULL' is now a default for parse_mtd_partitions, don't specify
this in every driver, instead pass NULL to force parse_mtd_partitions
to use default.

Convert to mtd_device_register() and remove the CONFIG_MTD_PARTITIONS
preprocessor conditionals as partitioning is always available.

Remove the ARM dependency from the generic "onenand" platform device
driver. This change makes the driver useful for other architectures as
well. Needed for the SuperH kfr2r09 board.
Apart from the obvious Kconfig bits, the most important change is the move
away from ARM specific includes and platform data. Together with this
change the only in-tree board code gets an update, and the driver name is
also changed gracefully break potential out of tree drivers.
The driver is also updated to allow NULL as platform data together with a
few changes to make use of resource_size() and dev_name().

This patch fixes the bug reported in
http://bugzilla.kernel.org/show_bug.cgi?id=11681.
"Lots of device drivers register a 'struct device_driver' with
the '.bus' member set to '&platform_bus_type'. This is wrong,
since the platform_bus functions expect the 'struct device_driver'
to be wrapped up in a 'struct platform_driver' which provides
some additional callbacks (like suspend_late, resume_early).
The effect may be that platform_suspend_late() uses bogus data
outside the device_driver struct as a pointer pointer to the
device driver's suspend_late() function or other hard to
reproduce failures."(Lothar Wassmann)

We can use the two methods to wait.
1. polling: read interrupt status register
2. interrupt: use kernel ineterrupt mechanism
To use interrupt method, you first connect onenand interrupt pin to your
platform and configure interrupt properly

Include fixes for 2.6.14-git11. Should allow to remove sched.h from
module.h on i386, x86_64, arm, ia64, ppc, ppc64, and s390. Probably more
to come since I haven't yet checked the other archs.
