ARM: dove: Fix legacy get_irqnr_and_base
Commit5d6bed2a9c
("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] Signed-off-by: Nicolas Pitre <nico@linaro.org> Fixes:5d6bed2a9c
