staging: comedi: amplc_dio200: Replace printk calls

Browse source 
Replace the printk calls with dev_info, dev_err, etc.  There were some
consecutive printk calls without newlines which now scnprintf into a
temporary buffer and this bit of code has been factored out into new
function dio200_report_attach().
