Rename mc_* to plda_* for common data structures,
setup and IRQ functions.
The modification includes:
- Add related data structures of PCIe host instance.
mc_pcie --> plda_pcie_rp (Get most of data members)
mc_msi --> plda_msi
- function rename list:
mc_pcie_setup_window() --> plda_pcie_setup_window()
mc_pcie_setup_windows() --> plda_pcie_setup_iomems()
mc_allocate_msi_domains() --> plda_allocate_msi_domains()
MSI interrupts related functions and IRQ domain
(primary function is mc_handle_msi()):
mc_handle_msi() --> plda_handle_msi()
INTx interrupts related functions and IRQ domain
(primary function is mc_handle_intx()):
mc_handle_intx() --> plda_handle_intx()
