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.
