sh: hd64461: Handle virq offset for offchip IRQ base and HD64461 IRQsh-for-v6.5-tag2for-v6.5
A recent change to start counting SuperH IRQ #s from 16 breaks support for the Hitachi HD64461 companion chip. Move the offchip IRQ base and HD64461 IRQ # by 16 in order to accommodate for the new virq numbering rules. Fixes: a8ac2961148e ("sh: Avoid using IRQ0 on SH3 and SH4") Signed-off-by: Artur Rojek <contact@artur-rojek.eu> Reviewed-by: Geert Uytterhoeven <geert+renesas@glider.be> Reviewed-by: John Paul Adrian Glaubitz <glaubitz@physik.fu-berlin.de> Link: https://lore.kernel.org/r/20230710233132.69734-1-contact@artur-rojek.eu Signed-off-by: John Paul Adrian Glaubitz <glaubitz@physik.fu-berlin.de>
