Random drivers should not override a user configuration of core knobs
(e.g., CONFIG_DMA_CMA=n). Use "imply" instead, to still respect
dependencies and manual overrides.

"This is similar to "select" as it enforces a lower limit on another
 symbol except that the "implied" symbol's value may still be set to n
 from a direct dependency or with a visible prompt."

Implying DMA_CMA should be sufficient, as that depends on CMA.

Note: If this is a real dependency, we should use "depends on DMA_CMA"
instead -  but I assume the driver can work without CMA just fine --
esp. when we wouldn't have HAVE_DMA_CONTIGUOUS or CMA right now.
