dmaengine: std_dma40: fix kernel-doc warnings and spelling 



Correct kernel-doc warnings as reported by kernel test robot:

ste_dma40.c:57: warning: Excess struct member 'dev_tx' description in 'stedma40_platform_data'
ste_dma40.c:57: warning: Excess struct member 'dev_rx' description in 'stedma40_platform_data'

Correct spellos as reported by codespell.
