platform/x86/intel/pmt: Block mmap when callback is present

With the introduction of the .read_telem() callback, control
for access to a devices data area must be done by the callback
owner.

This means that an area cannot be mmap-ed with the default PMT
handler.

If the .read_telem() callback is present, do not support mmap.
