hwc: Set DMA state at the start of composition

Browse Source 
* Set DMA state at the start of the composition cycle
based on the following.

Set it to LINE_MODE if the number of active rotator
sessions are 0.

Set it to BLOCK_MODE if
** A yuv-layer for any display-device requires rotation
** (or) mExtOrientation is set
** (or) mBufferMirrorMode is set

* Separate out the reset helper function into more
modular ones
