Remove dependencies on HAS_DMA where a Kconfig symbol depends on another
symbol that implies HAS_DMA, and, optionally, on "|| COMPILE_TEST".
In most cases this other symbol is an architecture or platform specific
symbol, or PCI.

Generic symbols and drivers without platform dependencies keep their
dependencies on HAS_DMA, to prevent compiling subsystems or drivers that
cannot work anyway.

This simplifies the dependencies, and allows to improve compile-testing.

Notes:
   - FSL_FMAN keeps its dependency on HAS_DMA, as it calls set_dma_ops(),
     which does not exist if HAS_DMA=n (Do we need a dummy? The use of
     set_dma_ops() in this driver is questionable),
   - SND_SOC_LPASS_IPQ806X and SND_SOC_LPASS_PLATFORM loose their
     dependency on HAS_DMA, as they are selected from
     SND_SOC_APQ8016_SBC.

Looks good.
