Hence AM654 will use the same pci wrapper driver pci-keystone.c In preparation for adding AM654 support, cleanup pci-keystone driver here. Most of the cleanups here are trivial with major modification being merging pci-keystone-dw.c and pci-keystone.c Cleaning-up irq handling in the RFC series is dropped here as it has few comments to be addressed. Other patches which are part of the RFC series will be sent separately.
