comedi: ni_pcimio: set PCI-6220 dio_speed and ai_fifo_depth from NI specs

Browse Source 
The PCI-6220 board entry was missing .dio_speed, unlike the PXI-6220 and
the other 622x boards in the table. Set it to 1000 ns to match those
entries and the 1 MHz maximum DI/DO sample clock on Port 0 in the NI
PCI/PXI-6220 specifications.

Also update .ai_fifo_depth for PCI-6220 and PXI-6220 from 512 to 4095
samples, matching the documented AI input FIFO size and the rest of the
622x entries.
