pp->msi_data is set in dw_pcie_msi_init, which is a global function
called from vendor specific code. You can have your own
keystone_pcie_msi_init and then you do not need above changes.

Yes, can be. You can send changes in 2 or 3 patches as you wish, but I
believe that should be able to solve problem in best way.
