Since commit f44f7f9 (RTC: Initialize kernel state from RTC)
rtc_device_register reads the programmed alarm. As reading the alarm
needs to take the mc13xxx lock, release it before calling
rtc_device_register.This fixes a deadlock during boot:

The RTC subsystem has a number of accessors that are available via
include/linux/rtc.h. However many of these interfaces are not
available for use if CONFIG_RTC_CLASS=m.So in order to support wider use of the RTC in the kernel, I'm
removing the tristate config option for a bool, so that code can
easily be conditionalized if the RTC class is present or not.Signed-off-by: John Stultz

We call rtc_read_alarm from rtc_device_register, so it is important
that the rtc device is fully initialized prior to registration.rtc-max8925 sets drvdata after register, so the rtc_read_alarm code
dereferences a NULL pointer.Call dev_set_drvdata before rtc_device_register.

Some platforms cannot implement read_persistent_clock, as
their RTC devices are only accessible when interrupts are enabled.
This keeps them from being used by the timekeeping code on resume
to measure the time in suspend.The RTC layer tries to work around this, by calling do_settimeofday
on resume after irqs are reenabled to set the time properly. However,
this only corrects CLOCK_REALTIME, and does not properly adjust
the sleep time value. This causes btime in /proc/stat to be incorrect
as well as making the new CLOCK_BOTTTIME inaccurate.This patch resolves the issue by introducing a new timekeeping hook
to allow the RTC layer to inject the sleep time on resume.The code also checks to make sure that read_persistent_clock is
nonfunctional before setting the sleep time, so that should the RTC's
HCTOSYS option be configured in on a system that does support
read_persistent_clock we will not increase the total_sleep_time twice.CC: Arve Hjønnevåg

The rtc_device_register() call has changed semantics so that it
