ACPI / thermal: Add check of "_TZD" availability and evaluating result

Some machines don't provide _TZD, so check the availability of it
before carrying out futher operations.

If _TZD is present, also check the result of its evaluation.

ACPI / EC: Add ASUSTEK L4R to quirk list in order to validate ECDT

The ECDT of ASUSTEK L4R doesn't provide correct command and data
I/O ports.  The DSDT provides the correct information instead.

For this reason, add this machine to quirk list for ECDT validation
and use the EC information from the DSDT.
