The RTC RV3029 handles different types of alarms : seconds, minutes, ...
These alarms can be enabled or disabled individually using an AE_x bit
which is the last bit (BIT(7)) on each alarm registers.
To prepare the alarm IRQ support, the current code enables all the alarm
types by setting each AE_x to 1.
It also fixes others alarms issues :
- month and weekday errors : it was performing -1 instead of +1.
- wrong use of bit mask with bin2bcd

This adds support to
- enable/disable the thermometer
- set the temperature scanning interval
- read the current temperature that is used for temp compensation.

It also fixes the definition of the trickle charger bit masks.

After the switch to devm_* functions and the removal of
rtc_device_unregister(), the 'remove' function does not do anything.

In the disable AIE irq code path, current code passes "1" to enable
parameter of rv3029c2_rtc_i2c_alarm_set_irq(). Thus it does not disable

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.
