Use the devres managed resource functions in the probe routine.  Also
affects the remove routine where the previously used free and release
functions are not needed.

The devm_* functions eliminate the need for manual resource releasing and
simplify error handling.  Resources allocated by devm_* are freed
automatically on driver detach.

Remove RTT interrupt handling, since PIE mode interrupts are now better
emulated in generic code via an hrtimer we have no need for this, and
there is no codepath in the driver that enables these periodic interrupts
anyway.

If the rtc reports the time might be invalid due to oscillator failure,
M41T93_FLAG_OF flag must not be reset by get_time() as the read operation
doesn't make the time valid.

Without this patch, only the first get_time() reported an invalid time,
the second get_time() reported a valid time althought the reported time is
probably wrong due to oscillator failure.

Instead of resetting in get_time(), with this patch M41T93_FLAG_OF is
reset in set_time() when a valid time is to be written.

Some DS13XX devices have "trickle chargers".  Its configuration register
is at different locations, the setup is the same, though.  Since the
configuration is board specific, introduce a platform_data to this driver.
Tested with a DS1339 on a custom board.

RTC_DRV_IMXDI and RTC_MXC are on-chip RTC modules, so move them under
"on-CPU RTC drivers" selection menu.

While at it change the dependency of RTC_DRV_IMXDI from ARCH_MX25 to
SOC_IMX25.
