cold-flash: accept also OMAP3630 in the ASIC ID

Browse Source 
Accept also OMAP3630 in the ASIC ID offset 4. With this patch it's
possible communicate also with N950/N9. When plugging in the USB cable
into a powered-off device, it seems to start in cold-flash mode, and
currently 0xFFFF fails with "Invalid ASIC ID."

So far only loading & booting kernel with "0xFFFF -m kernel:zImage -l -b"
has been tested, and it works.

WARNING: When booting a self-made kernel on N950/N9, NOLO will detect this
and will permanently show a crappy disclaimer about warranty voided during
the boot, even if you boot again with a stock Nokia kernel. This may also
impact some SW functionality. I have no idea how to reset this condition.
