[0/8] rtc: sh: fight the bitrot

Message

When looking for hardware that supports UIE via alarm irqs, I came
across the Renesas Genmai board and its rtc-sh driver. The driver
basically works but there is still a lot of cruft left which is not
needed since the RTC core now uses the timerqueue.

Patch 1 is actually a bugfix for DT systems. Without it, alarm
interrupts don't work. I suggest backporting it to stable.

The other patches are mostly removals. This is why the diffstat looks so
nice. More descriptions in the individual patches.

Looking forward to comments.
