Subject: [PATCH v2 14/21] mtd: Remove depends on HAS_DMA in case of platform dependency
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.

v2:
- Add Reviewed-by, Acked-by,
- Drop RFC state,
- Drop new dependency of MTD_NAND_MARVELL on HAS_DMA,
- Split per subsystem.
