PCI: dwc: Enable write permission for Class Code, Interrupt Pin updates

Browse source

dw_pcie_setup_rc() contains fixes to update the Class Code and Interrupt
Pin registers, but the fixes don't actually work because these registers
are read-only.

Enable write permission before updating the Class Code and Interrupt
Pin.
