[PATCH] MIPS: Fix PCI host bridge map_irq() hook section mismatches

From: Lorenzo Pieralisi
Date: Tue Sep 19 2017 - 06:47:19 EST

Commit 04c81c7293df ("MIPS: PCI: Replace pci_fixup_irqs() call with host
bridge IRQ mapping hooks") allowed to move the PCI irq fixup to the new
host bridge map/swizzle_irq() hooks mechanism. Those hooks can also be
called after boot completed - with all __init/__initdata/__initconst
sections freed by the kernel - therefore functions called by them (and
the data they refer to) must not be marked as
__init/__initdata/__initconst lest compilation triggers section
mismatches warnings.

Fix all the boards 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.

Fixes: 04c81c7293df ("MIPS: PCI: Replace pci_fixup_irqs() call with host
bridge IRQ mapping hooks")
