EC: Add Lenovo H8
Move the EC support code from the X60 mainboard to a generic
driver, as this EC is used in many thinkpads. Also move the
ACPI code to this directory for this reason.
This patch also adds a chip config, so that the initial setting
for basic register can be specified in devicetree.cb
