omap: dispc: force L3_1 CD to NOSLEEP when dispc module is active.
With the DSS FIFO optimizations, ramdom lockups and reboots are seen. It has been identified that L3_1 CD is idling and not responding to the traffic initiated by DSS. The Workaround suggested by Hardware team is to keep the L3_1 CD in NO_SLEEP mode, when DSS is active. Once DSS module is switched to idle mode, put L3_1 CD to HW_AUTO. This patch was reverted by 169c5f0, but a test case was found that reproduces the original problem.
