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

commit 7c28a35e19 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: a8ac296114 ("sh: Avoid using IRQ0 on SH3 and SH4")
