staging: comedi: vmk80xx: cleanup analog output subdevice init
Change the type for the analog output 'ao_chans' boardinfo to match
the comedi_subdevice type it is set to. For aesthetic reasons, rename
the variable also.
Rename the (*insn_write) and (*insn_read) functions for the analog
output subdevice to make grepping easier.
For aesthetic reasons, add some whitespace to the subdevice init.
