OMAP: DSS2: VENC: make 20ms venc bug-fix sleep optional 



There's a 20ms sleep after VENC reset. It's unknown what bug this
circumvents and on what platforms. Add a Kconfig option to disable the
sleep.

	  There is a 20ms sleep after VENC reset which seemed to fix the

	  reset. The reason for the bug is unclear, and it's also unclear

	  on what platforms this happens.



	  This option enables the sleep, and is enabled by default. You can

	  disable the sleep if it doesn't cause problems on your platform.
