ESP: fix ESP DMA access when DMA is not enabled
Sending ESP a command caused it to trigger DMA immediatelyeven if DMA was not enabled at the DMA controller.
Add a signal from DMA controller to ESP to tell ESP about changes inDMA enable bit. Also use the correct function for setting up GPIO outputs....
esp: use CamelCaseFunc for function types
