mfd: palmas: Add rtc irq number as irq resource for palmas-rtc

Browse Source 
Palma RTC is capable of generating alarm interrupt. Pass the alarm interrupt
as IRQ_RESOURCE for palmas-rtc sub device driver so that rtc driver can get
irq as platform_get_irq().

Also pass the irq domain in mfd_add_devices() to properly offset the irqs for
sub devices. This is needed when adding device through DT.
