Use the wrapper functions for getting and setting the driver data using
platform_device instead of using dev_{get,set}_drvdata() with &pdev->dev,
so we can directly pass a struct platform_device.

This chip has a control register and can prevent altering saved clock.
Without this patch we could have:

The patch enables write access to rtc before the driver tries to write
time and re-disables when time data is written.

Android expects the RTC to have second resolution.  On ab8540 cut2 RTC
block has a new register which allows setting seconds for wakeup alarms.

Existing registers (minutes hi, mid and low) have seen their offsets
changed. Here is the new mapping:
  * AlarmSec     (A) 0x22
  * AlarmMinLow  (M) from 0x8 to 0x23
  * AlarmMinMid  (M) from 0x9 to 0x24
  * AlarmMinHigh (M) from 0xA to 0x25
