cros_ec_debugfs: Pass proper struct sizes to cros_ec_cmd_xfer()
We should output or receive every byte in the param / reply struct, unrelated to the pointer size. Signed-off-by: Shawn Nematbakhsh <shawnn@chromium.org> Reviewed-by: Gwendal Grignou <gwendal@chromium.org> [bleung: Picked from crosreview.com/444085 for cros_ec_debugfs.c only. cros_ec.c upstream had a different cros_ec_sleep_event which didn't have the sizeof issue] Signed-off-by: Benson Leung <bleung@chromium.org>
