Michael J. Ruhl 0c32840763 platform/x86/intel/pmt: allow user offset for PMT callbacks ...

Usage of the telem sysfs file allows for partial reads at an offset.
The current callback method returns the buffer starting from offset 0
only.

Include the requested offset in the callback and update the necessary
address calculations with the offset.

Note: offset addition is moved from the caller to the local usage. For
non-callback usage this is unchanged behavior.
