They got accidently removed by f0fba2a (ASoC: multi-component - ASoC
Multi-Component Support). Reintroduce them and get rid of the
superfluous defines because the fiq-driver has its own hardcoded values.

SSI counts in words, the DMA engine in bytes. (Wrong) factor got removed
in bf974a0 (ASoC i.MX: switch to new DMA api).

Checking if IMX_SSI_DMA is set and then set it again is useless.
