staging: comedi: amplc_pc236: split pc236_boards[] into ISA & PCI
Split `pc236_boards[]` into `pc236_isa_boards[]` for ISA cards and `pc236_pci_boards[]` for PCI cards (there is only one of each). Only initialize the board name look-up members of `struct comedi_driver amplc_pc236_driver` if the ISA part of the driver is enabled in the kernel config (`CONFIG_COMEDI_AMPLC_PC236_ISA`) using the array of ISA boards (`pc236_isa_boards[]`). The driver doesn't allow manual configuration of PCI devices, so there is no point having the comedi core match the names of the PCI boards before it calls our driver's legacy attach routine (`pc236_attach()`).
