servo_v4: add initial servo_v4 build
Add initial servo_v4 build, GPIOs, etc. Supports most features other than PD passthrough. BUG=chromium:571476 BRANCH=None TEST=updated servod is able to control gpio, gpio extender on servo v4 Change-Id: I71c9cb2bf24b732dd6a2e101d7b1c849c9f88af8 Signed-off-by: Nick Sanders <nsanders@google.com> Reviewed-on: https://chromium-review.googlesource.com/332803 Commit-Ready: Nick Sanders <nsanders@chromium.org> Tested-by: Nick Sanders <nsanders@chromium.org> Reviewed-by: Todd Broch <tbroch@chromium.org>
