media_codecs: Cleanup & update (mikeNG)
* Comment out codecs that require proprietary libraries we do not have
* Update for lollipop
* Disable software codecs
msm7x30: Disable TARGET_CPU_SMP (mikeNG)
msm7x30: Disable Atlas service (mikeNG)
Disable Atlas service to avoid memory overhaed caused by it.

Drawbacks in Atlas service:
- Fixed size of canvas: whether the drawebles are in use or not always
                        resides in memory.
- Choosing drawables: It chooses the drawables to pre-load based on
                      dimensions, rather than number of requested apps.
add support for Legacy OMX (Kirmaniarslan)
