 From a quick look into Synopsys DW ip library, it probably matches 
dw_apb_ictl best and should be named accordingly. Next round will
name the source dw_apb_ictl.c and corresponding compatible
"snps,dw-apb-ictl".

In addition, it looks like the ip can support up to 64 irqs. For orion
irq, I have used a "mavell,#interrupts" to allow to pass the number of
supported irqs. Above driver should also exploit a similar
snps-prefixed property.
