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.

Quoted 9 lines

Similar functionality was turned on by acpi_fake_ecdt=1 command line before. Now it is on all the time.

Steps to reproduce: boot (or try to)

I'm not sure that I understand this report ;)

Michal, pleas track it as a post-2.6.22 regression.

Daniel, if you have a patch which you think is needed for 2.6.23 can you please send it?
