Actual RPM is now read from LPC mapped space. Modify this command to return target RPM so we can verify EC receives target RPM. Signed-off-by: Vic Yang <victoryang@chromium.org> BUG=chrome-os-partner:8238 TEST=Get the same value after setting target RPM. Change-Id: I9bcc9edd327cec1311b51fd0fcbc4a43b353daff
