platform/x86/intel/pmt: Use PMT callbacks
PMT providers may require device specific actions before their telemetry
may be read. If the read_telem() is assigned, call it instead of
memcpy_fromio() and return. Since this needs to be done in multiple
locations, add pmt_telem_read_mmio() as a wrapper function to perform this
and any other needed checks.
