drm/ingenic: Simplify code by using hwdescs array

Browse source

Instead of having one 'hwdesc' variable for the plane #0, one for the
plane #1 and one for the palette, use a 'hwdesc[3]' array, where the
DMA hardware descriptors are indexed by the plane's number.

v2: dma_hwdesc_addr() extended to support palette hwdesc. The palette
    hwdesc is now hwdesc[3] to simplify things. Add
    ingenic_drm_configure_hwdesc*() functions to factorize code.
