[PATCH 3.19.y-ckt 081/128] ARM: orion5x: Fix legacy get_irqnr_and_base

[Kamal Mostafa]

3.19.8-ckt12 -stable review patch.  If anyone has any objections, please let me know.

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

From: Nicolas Pitre <nicolas.pitre@xxxxxxxxxx>

commit 4d2ec7e206ae03a51dfbdedc120ce88d403ec926 upstream.

Commit 5be9fc23cd ("ARM: orion5x: fix legacy orion5x IRQ numbers") shifted
IRQ numbers by one but didn't update the get_irqnr_and_base macro
accordingly.  This macro is involved when CONFIG_MULTI_IRQ_HANDLER
is not defined.

[jac: 5d6bed2a9c went in to v4.2, but was backported to v3.18]
