target: msm8226: Use DMA pipe for splash logo

8x26 has only a single RGB pipe. Currently if userspace calls
prepare on RGB pipe during handoff, then fallback case happens
and VIG pipe is allocated. This leads to issues in case of secure
video content playback as VIG pipe is not available. To avoid
such issues, use DMA pipe instead of RGB for continuous splash
handoff.
