Corstone-1000 performs PSA ADAC authentication while the device is in CM. TF-M runtime provisioning then changes the lifecycle state and resets the platform, which loses the authenticated debug permissions. Add a Secure Debug build option that skips TF-M runtime provisioning. This keeps the device in CM and avoids the provisioning reset until a reset-safe design can preserve DCU_EN across reset and apply it from BL2. Update the Secure Debug guide to use Arm Development Studio's built-in PSA-ADAC manager and obtain test credentials without building the external SDM library. Document the connection setup and verify that the system boots after authentication. Signed-off-by: Ahmed Gomaa <ahmed.gomaa@arm.com>
