PDC interrupt controller driver do not use second reg. Remove it.
This is a DT file, not a driver. What the driver does is irrelevant.

The real question is: what does this range do?



This is to set interrupt type in SPI config for which there was a change [1] but has not gone in for upstream PDC driver.

The second reg is not used in upstream PDC driver, probably when posting downstream DT changes for sm8350/sm8250 it was carried in device node as is.

As its not mentioned in bindigs as well, dtbs_check reports it as additional reg when converted to yaml.
