ASoC: fsl: fsl_dma: Use true/false for boolean init

Bool initializations should use true and false.  Bool tests don't need
comparisons.  Based on contributions from Joe Perches, Rusty Russell
and Bruce W Allan.

The semantic patch that makes this change is available
in scripts/coccinelle/misc/boolinit.cocci.
