Vale caught a use of Deep Sleep

Add DSS plus Deep Sleep low power mode, a new suspend mode where the Display Subsystem remains powered to show a static image while the rest of the system enters Deep Sleep. Signed-off-by: Akashdeep Kaur <a-kaur@ti.com>

Add power consumption data for DSS plus Deep Sleep mode. This mode consumes more power than standard Deep Sleep (14.07 mW) due to the active display subsystem with FIFO replay. Signed-off-by: Akashdeep Kaur <a-kaur@ti.com>

Add DSS plus Deep Sleep mode to Key Release References section, highlighting the new display subsystem self-refresh capability that allows showing static images during system suspend. Signed-off-by: Akashdeep Kaur <a-kaur@ti.com>
