staging: comedi: addi_common.c: remove i_ADDI_Reset()

The addi_apci_035 and addi_apci_1500 are the only drivers left that use
this function in addi_common.c. The function simply calls the 'reset'
function that is in the boardinfo of the driver. Both drivers use the
same 'reset' function for all boardnfo entries.

Remove the i_ADDI_Reset() function as well as the 'reset' boardinfo and
just call the 'reset' function directly.

The i_ADDI_Reset() is called by addi_auto_attach() in addi_common.c after
a sucessful attach. Modify the (*auto_attach) in the drivers to call the
'reset' function directly and remove it from addi_auto_attach().
