Subject: [PATCH] staging: comedi: pcl818: introduce pcl818_ai_clear_eoc()

Introduce a helper function to clear the end-of-conversion flag.

This flag is set when an analog input conversion is finished and the
hardware generates an interrupt request. Writing any value to the
register resets the flag and re-enables the interrupt.

Remove the clearing of the flag in pcl818_handle_eoc(). The interrupt
function will handle clearing the flag.
