Subject: [PATCH 4.20 29/50] ARM: iop32x/n2100: fix PCI IRQ mapping

4.20-stable review patch.  If anyone has any objections, please let me know.

------------------

From: Russell King <rmk+kernel@...linux.org.uk>

commit db4090920ba2d61a5827a23e441447926a02ffee upstream.

Booting 4.20 on a TheCUS N2100 results in a kernel oops while probing
PCI, due to n2100_pci_map_irq() having been discarded during boot.
