comedi: ni_at_a2150: Add sanity checks for I/O base address

The "ni_at_a2150" driver uses an admin-supplied configuration option
(`it->options[0]`) to configure the I/O port base address of an AT-A2150
series board.  It currently allows any base address to be configured but
the hardware only supports base addresses (configured by on-board
jumpers) in the range 0 to 0x3E0 on 32-byte boundaries.

Add a sanity check to ensure the device is not configured at an
unsupported base address.
