04c81c7293("MIPS: PCI: Replace pci_fixup_irqs() call with host bridge IRQ mapping hooks") moved the PCI IRQ fixup to the new host bridge map/swizzle_irq() hooks mechanism. Those hooks can also be called after boot, when all the __init/__initdata/__initconst sections have been freed. Therefore, functions called by them (and the data they refer to) must not be marked as __init/__initdata/__initconst lest compilation trigger section mismatch warnings. Fix all the board files map_irq() hooks by simply removing the respective __init/__initdata/__initconst section markers and by adding another persistent hook IRQ map for the txx9 board files.
