The Kconfig currently controlling compilation of this code is:
drivers/misc/Kconfig:config ARM_CHARLCD
drivers/misc/Kconfig: bool "ARM Ltd. Character LCD Driver"
...meaning that it currently is not being built as a module by anyone.
Lets remove the modular code that is essentially orphaned, so that
when reading the driver there is no doubt it is builtin-only.
We explicitly disallow a driver unbind, since that doesn't have a
sensible use case anyway, and this driver did not have a ".remove"
function coded for non-modular drivers either.
Since module_platform_driver() uses the same init level priority as
builtin_platform_driver() the init ordering remains unchanged with
this commit.
We don't replace module.h with init.h since the file already has that.
We also delete the MODULE_LICENSE tag etc. since all that information
is already contained at the top of the file in the comments.

This patch proposes to remove the use of the IRQF_DISABLED flag
It's a NOOP since 2.6.35 and it will be removed one day.

The driver core clears the driver data to NULL after device_release
or on probe failure, since commit 0998d06310
(device-core: Ensure drvdata = NULL when no driver is bound).
Thus, it is not needed to manually clear the device driver data to NULL.

This patch uses module_platform_driver_probe() macro which makes
the code smaller and simpler.

This adds a driver for the character LCD found on the ARM Versatile
and RealView Platform Baseboards. It doesn't do very much more than
display the text "ARM Linux" on the first line and the linux banner
on the second line, but that's still useful.
