Subject: [PATCH v3 0/9] PCI: DWC/Keystone: MSI configuration cleanup

This series tries to address the comments discussed in [1] w.r.t
removing Keystone specific callbacks defined in dw_pcie_host_ops.

This series also tries to cleanup the Keystone interrupt handling
part.

Changes from v2:
*) Removed patch that modifies ks_pcie_legacy_irq_handler() to check the
   IRQ_STATUS of INTA/B/C/D. Lorenzo's comment to create a matrix
   LinuxIRQ x INTx will be added in AM654x PCIe support series
*) ks_pcie_legacy_irq_handler() is made to use hwirq to get IRQ offset
   instead of virq.
*) default msi_irq_chip is assigned in dw_pcie_host_init() once keystone
   assigns its msi_irq_chip
*) Fixed other minor comments from Lorenzo and Bjorn

Changes from v1:
*) Removed "PCI: keystone: Use "dummy_irq_chip" instead of new irqchip
for legacy interrupt handling" from the patch series. It should be
handled differently.

*) Added Gustavo's ACKed by and fixed a commit message.
