Subject: [PATCH 1/4] iio: imu: adis: Add self_test_reg variable
From: Nuno Sá <nuno.sa@...log.com>
This patch adds a dedicated self_test_reg variable. This is also a step
to let new drivers make use of `adis_initial_startup()`. Some devices
use MSG_CTRL reg to request a self_test command while others use the
GLOB_CMD register.
