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.

Instead of using legacy suspend/resume methods, using newer dev_pm_ops
structure allows better control over power management.

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, __devinitdata,
__devinitconst, 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.

The patch renames puv3_rtcdrv to puv3_rtc_driver, so that modpost will know
that this is simply a list of pointers to driver functions, in which case
the section mismatch is OK. (Thanks Michal Marek)

This patch converts the driver to use the module_platform_driver()
macro which makes the code smaller and a bit simpler.

Several fixes as well where the +1 was missing.
Done via coccinelle scripts like:
@@
struct resource *ptr;
@@
- ptr->end - ptr->start + 1
+ resource_size(ptr)
and some grep and typing.
Mostly uncompiled, no cross-compilers.

The patch moves rtc driver for PKUnity-v3 SoC from arch/unicore32/kernel/
to drivers/rtc/, with renaming it to rtc-puv3.c.
Also, Kconfig, Makefile, and MAINTAINERS are modified correspondingly.
