The Zynq UltraScale+ Technical Reference Manual (UG1085) documents the SPI values in Table 11-3 with the following note:
"The SPI index is mapped to the GIC interrupt ID# as: GIC-SPI[N] = ID# (N+32)".
In Linux, the .dtsi contains the actual interrupt id, and the internal driver/core will take care of the required arithmetics.
Note: Stand-alone will follow the above formula and update the interrupt id accordingly.
