From: Manivannan Sadhasivam <manivannan.sadhasivam@linaro.org>

Current error message just prints the contents of PARF_INT_ALL_STATUS
register as if like the IRQ event number. It could mislead the users.
Reword it to make it clear that the error message is actually showing the
interrupt status register to help debug spurious IRQ events.
