However currently the register definitions in 'cxl.h' have a definition for PSL9_FIR2 that actually points to PSL9_FIR_MASK register in the P1 area at offset 0x308. So this patch renames the def PSL9_FIR2 to PSL9_FIR_MASK and updates the references in the code to point to the new identifier. It also removes the code to dump contents of FIR2 (FIR_MASK actually) in cxl_native_irq_dump_regs_psl9().
