[PATCH 11/46] staging: comedi: adl_pci9111: cleanup ao resolution

The 'ao_resolution' in the boardinfo is not used. Remove it.
Rename the 'ao_resolution_mask' to 'ao_maxdata', this information
is copied to the ao subdevice 'maxdata'.
Remove the PCI9111_AO_RESOLUTION* defines and just open-code the
maxdata in the boardinfo.
Remove the mask of the output data in pci9111_ao_insn_write(),
the comedi core insures that the data is valid.
