rtc: max8907: add missing select REGMAP_IRQ

commit 5d892919fdd0cefd361697472d4e1b174a594991 upstream.

I have hit the following build error:

  armv7a-hardfloat-linux-gnueabi-ld: drivers/rtc/rtc-max8907.o: in function `max8907_rtc_probe':
  rtc-max8907.c:(.text+0x400): undefined reference to `regmap_irq_get_virq'

max8907 should select REGMAP_IRQ
