tamsui: modifications for use with display-caf
*    Temporarily remove hwcomposer.msm7x27a till we find
     kk-2.7 adreno blobs that work
*    Use custom LPA buffer size as we now have two audio heaps in the kernel
     to fix playback stuttering issues
*    Enable BOARD_RECOVERY_SWIPE
*    Remove obsolete flags
