[PATCH] rtc: max8907: add missing select REGMAP_IRQ

[Corentin Labbe]

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

Fixes: 94c01ab6d7544 ("rtc: add MAX8907 RTC driver")
