ACPI / tools: Introduce ec_access.c - tool to access the EC
This userspace tool accesses the EC through the ec_sys debug driver
(through /sys/kernel/debug/ec/ec0/io).
The EC command/data registers cannot be accessed directly, because they
may be manipulated by the AML interpreter in parallel.
The ec_sys driver synchronizes user space (debug) access with the AML
interpreter.
