Subject: sh: hd64461: Handle virq offset for offchip IRQ base and HD64461 IRQ

From: Artur Rojek <contact@xxxxxxxxxxxxxx>

commit 7c28a35e19fafa1d3b367bcd3ec4021427a9397b upstream.

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")
