s/dma/DMA/ above for consistency.

Add blank line here if this is a paragraph break.

s/drived/derived/

This patch doesn't add anything related to SCMI, so this paragraph
seems like a distraction.

The first paragraph seems a bit of a distraction too, since the patch
doesn't say anything about DMA register space or interrupt.
