Adds support for RTC device inside PM8941 PMIC. The RTC in this PMIC
have two register spaces. Thus the rtc-pm8xxx is slightly reworked to
reflect these differences.
The register set for different PMIC chips are selected on DT compatible
string base.

Add support for describing the PM8921/PM8058 RTC in device tree.
Additionally:
- drop support for describing the RTC using platform data,
as there are no current in tree users who do so.
- make allow_set_time a device-specific flag, instead of mucking
with the rtc_ops

Now that the parent mfd driver has been made to work again, and has been
reworked to create a regmap instance intended for its children to use,
rework the pm8xxx driver to use the regmap API for its register
accesses.

This patchset is based on Stephen Boyd's PM8921 modernization/cleanups
(http://lkml.kernel.org/g/1393441166-32692-1-git-send-email-sboyd@codeaurora.org),
and allows for this RTC driver to be usable again.
This patch (of 6):
Before performing additional cleanups to this driver, do the easy cleanups
first.

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.

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.

This patch converts the drivers in drivers/rtc/* to use the
module_platform_driver() macro which makes the code smaller and a bit

Add support for PMIC8xxx based RTC. PMIC8xxx is Qualcomm's power
management IC that internally houses an RTC module. This driver
communicates with the PMIC module over SSBI bus.
