ACPI: EC: If ECDT is not found, look up EC in DSDT.
Some ASUS laptops access EC space from device _INI methods, but do not
provide ECDT for early EC setup. In order to make them function properly,
there is a need to find EC is DSDT before any _INI is called.
Similar functionality was turned on by acpi_fake_ecdt=1 command line
before. Now it is on all the time.
