[PATCH v2] sh: hd64461: fix virq offsets

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")

v2: Make the IRQ base offset an explicit (64 + 16), as per review.
