[PATCH 12/13] PCI: xilinx-nwl: Replace device * with platform_device *

[Fan Fei <ffclaire1224@gmail.com>]

Some PCI controller struct contain "device *", while others contain
"platform_device *". Unify "device *dev" to "platform_device *pdev" in
struct nwl_pcie, because PCI controllers interact with platform_device
directly, not device, to enumerate the controlled device.
