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.
