hwmon/coretemp: Handle large core ID value

commit 7108b80a

 upstream.

The coretemp driver supports up to a hard-coded limit of 128 cores.

Today, the driver can not support a core with an ID above that limit.
Yet, the encoding of core ID's is arbitrary (BIOS APIC-ID) and so they
may be sparse and they may be large.

Update the driver to map arbitrary core ID numbers into appropriate
array indexes so that 128 cores can be supported, no matter the encoding
of core ID's.
