staging: comedi: addi_apci_3xxx: absorb apci3xxx_reset()

All the boards supported by this driver use the same 'reset' callback
in the boardinfo. Absorb the reset function, apci3xxx_reset(), from
hwdrv_apci3xxx.c directly into the driver.

Remove i_ADDI_Reset(), which indirectly called the reset function, and
just call apci3xx_reset() directly. Remove the 'reset' callback from
the boardinfo.
