For PCI boards, the `auto_attach` handler, `pc236_auto_attach()`,
initializes `dev->board_ptr` to point to a `struct pc236_board`, but
leaves `dev->board_name` unchanged. The Comedi core will have
initialized `dev->board_name` to the `driver_name` string member of
`amplc_pc236_driver`. For consistency with ISA boards manually
configured by the `COMEDI_DEVCONFIG` ioctl via the legacy `attach`
handler, `pc236_attach()`, set `dev->board_name` to the `name` member of
the `struct pc236_board` pointed to by `dev->board_ptr`.
Both `pc236_attach()` and `pc236_auto_attach()` call
`pc236_common_attach()`, which also sets `dev->board_name` to the `name`
member of the `struct pc236_board`. Since this assignment no longer
changes anything, remove it.
A nice side-effect of this change is that the same owner name string is
used for requesting I/O regions (before the call the
`pc236_common_attach()`) as is used for requesting the IRQ handler
(during the call to `pc236_common_attach()`). It was already the same
for (manually configured) ISA boards, but is now the same for
(automatically configured) PCI boards.

Since only a single PCI board is supported by the driver, there is no
need to call `pc236_find_pci_board()` to find the a board entry with
matching PCI device ID in `pc236_pci_boards[]`. Just point to the entry
directly and remove the look-up function. In fact, there is no reason
for `pc236_pci_boards[]` to be an array, so change it to a non-array
variable and rename it to `pc236_pci_board`. Also, the `devid` member
of `struct pc236_board` is no longer needed as it was only used by the
look-up function, so remove it.

Since the legacy attach routine `pc236_attach()` is only called for
board names matching an entry in our array of ISA boards
`pc236_isa_boards[]`, and it is reasonable to expect all elements of
`pc236_isa_boards[]` to have their `bustype` member initialized
correctly to `isa_bustype`, don't bother checking the bus type in
`pc236_attach()`. Add `if (!DO_ISA) return -EINVAL` to optimize out the
remainder of the function if `CONFIG_COMEDI_AMPLC_PC236_ISA` is not
defined.

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()`).

Now that this driver no longer supports "manual" attachment of PCI
devices in its `attach` hook (`pc236_attach()`), it no longer has code
that searches for a suitable PCI device and increments its reference
