Rename mc_* to plda_* for IRQ functions and related
IRQ domain ops data instances.
MSI, INTx interrupt codes and IRQ init codes are all
can be re-used.
- function rename list:
mc_allocate_msi_domains() --> plda_allocate_msi_domains()
mc_init_interrupts() --> plda_init_interrupts()
mc_pcie_init_irq_domain() --> plda_pcie_init_irq_domains()
mc_handle_event() --> plda_handle_event()
get_events() --> mc_get_events()
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()
