mfd: db8500-prcmu: Fix irqdomain usage
This fixes two issues with the DB8500 PRCMU irqdomain: - You have to state the irq base 0 to get a linear domain for the DT case from irq_domain_add_simple() - The irqdomain was not used to translate the initial irq request using irq_create_mapping() making the linear case fail as it was lacking a proper descriptor. I took this opportunity to fix two lines of whitespace errors in related code as I was anyway messing around with it.
