dmaengine: shdma: Remove sh_dmae_slave_chan_id enum
This patch replaces the sh_dmae_slave_chan_id enum with an unsigned int. The purpose of this chainge is to make it possible to separate the slave id enums from the dmaengine header. The slave id enums varies with processor model, so in the future it makes sense to put these in the processor specific headers together with the pinmux enums.
