Subject: [PATCH v1 0/2] drivers: don't select DMA_CMA or CMA

Trying to set CONFIG_CMA=y with CONFIG_DMA_CMA=n revealed that we have
three drivers that select these options. Random drivers should not
override user settings of such core knobs. Let's use "imply DMA_CMA"
instead, such that user configuration and dependencies are respected.
