void GXS_LoadBGExtPltt(const void *pSrc, u32 destSlotAddr, u32 szByte);
This function uses DMA to transfer BG palette data to the sub 2D Engine BG
Extended palette. The transfer destination address (in the BG Extended palette) can be specified. The DMA channel that is used is GX_DMAID (defined in gxcommon.h). Both destSlotAddr and szByte must be 4-byte aligned. Call between
GXS_BeginLoadBGExtPltt and GXS_EndLoadBGExtPltt.
