davinci: build list of unused EDMA events dynamically
Currently, the edma_noevent list is passed from platform data.
But on some architectures, there will be many EDMA channels
which will not be used at all. This patch scans all the
platform devices and then builds a list of events which are
not being used. The unused event list will be used to allocate
EDMA channels in case of EDMA_CHANNEL_ANY usage instead of the
edma_noevent being used earlier for this purpose.
This patch is based on David Brownells's suggestion at
http://article.gmane.org/gmane.linux.davinci/15176.
