PCI: epf-test: Simplify pci_epf_test_raise_irq()
Change the interface of the function pci_epf_test_raise_irq() to directly
pass a pointer to the struct pci_epf_test_reg defining the test being
executed. This avoids the need for grabbing this pointer using the register
BAR address and simplifies the call sites as the IRQ type and IRQ numbers
do not have to be passed as arguments.
