ACPI: Provide /sys/kernel/debug/ec/...
This patch provides the same information through debugfs, which previously was
provided through /proc/acpi/embedded_controller/*/info
This is the gpe the EC is connected to and whether the global lock
gets used.
The io ports used are added to /proc/ioports in another patch.
Beside the fact that /proc/acpi is deprecated for quite some time,
this info is not needed for applications and thus can be moved
to debugfs instead of a public interface like /sys.
