Subject: [PATCH v2 00/21] PCI: Cleanup pci-keystone driver

The PCIe controller in AM654 uses Synopsys core revision 4.90a and uses
the same TI wrapper as used in keystone2 with certain modification.
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.

Changes from v1:
*) remove phy_reset in the cleanup PHY handling patch. It will be sent
   while adding AM654 support
*) Add a separate patch for using ERR_IRQ_STATUS instead of
   ERR_IRQ_STATUS_RAW
*) Split outbound window configuration into two patches. One which
   gets the number of outbound windows from DT and the other cleansup
   outbound window configuration.
