dmaengine: omap-dma: Fix dynamic lch_map allocation
The original patch did not done what it was supposed to be doing and even
worst it broke legacy boot (OMAP1).
The lch_map size should be the number of available logical channels in sDMA
and the od->dma_requests should store the number of available DMA request
lines usable in sDMA.
In legacy mode we do not have a way to get the DMA request count, in that
case we use OMAP_SDMA_REQUESTS (127), despite the fact that OMAP1510 have
only 31 DMA request line.
