Commit f44f7f96a20 ("RTC: Initialize kernel state from RTC") caused a
boot regression on the MRST platform.
The reason is that rtc_device_register() calls rtc_read_alarm() after
that change, which function does not have all driver data set up yet.
The rtc-mrst driver needs to call dev_set_drvdata() before rtc_device_register()
gets called.

Fix the following section mismatch warning.
WARNING: drivers/rtc/built-in.o(.data+0xa0): Section mismatch in reference from the variable vrtc_mrst_platform_driver to the function .init.text:vrtc_mrst_platform_probe()
The variable vrtc_mrst_platform_driver references the function __init vrtc_mrst_platform_probe()
If the reference is valid then annotate the variable with __init* or __refdata (see linux/init.h) or name the variable:
*_template, *_timer, *_sht, *_ops, *_probe, *_probe_one, *_console,

If we don't assign Moorestown specific wallclock init and ops function
the rtc/persisent clock code will use cmos rtc for access, this will
crash Moorestown in that the ioports are not present.
Also in vrtc driver, should avoid using cmos access to check UIP status.

With PIE mode interrupts now emulated in generic code via an hrtimer,
no one calls rtc_class_ops->irq_set_state(), so this patch removes it
along with driver implementations.

Some rtc drivers use the ioctl method instead of the alarm_irq_enable
method for enabling alarm interupts. With the new virtualized RTC
rework, its important for drivers to use the alarm_irq_enable instead.
This patch converts the drivers that use the AIE ioctl method to
use the alarm_irq_enable method. Other ioctl cmds are left untouched.
I have not been able to test or even compile most of these drivers.
Any help to make sure this change is correct would be appreciated!
