Enabling smart idle modes in DMA4_OCP_SYSCONFIG enables sDMA to enter
standby if only synchronized dma transfers are programmed and no transfer
is active. This is needed to enable CORE power domain inactivity during
audio playback.
Compile tested with omap_3430sdp_defconfig on l-o master. Compile+boot+audio
playback (aplay) tested on custom omap3 HW.
IMO, this could go to linux-omap directly, but PM-branch is ok as well.
