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.
