acpi_ec: Implement basic ACPI embedded controller API

Implement basic functions to read/write EC registers and send standard
ACPI EC commands. Those may prove useful in possible future
implementations of embedded controllers in flashrom and are required
to support EC firmware flashing on Tuxedo laptops.
