[PATCH v1] dma: fix typo in the comment

[Yan Zhen]

Correctly spelled comments make it easier for the reader to understand
the code.

Replace 'enngine' with 'engine' in the comment &
replace 'trascatioin' with 'transaction' in the comment &
replace 'descripter' with 'descriptor' in the comment &
replace 'descritpor' with 'descriptor' in the comment &
replace 'rgisters' with 'registers' in the comment.
