[PATCH 4.2.y-ckt 064/305] ARM: dove: Fix legacy get_irqnr_and_base

[Kamal Mostafa]

4.2.8-ckt2 -stable review patch.  If anyone has any objections, please let me know.

From: Nicolas Pitre <nicolas.pitre@xxxxxxxxxx>

commit c1c90728efa49eab81ae816718d84116a22b790e upstream.

Commit 5d6bed2a9c ("ARM: dove: fix legacy dove 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]
