staging: comedi: adl_pci9118: allocate private data in pci9118_common_attach()
The (*auto_attach) and legacy (*attach) both allocate the private data but
don't use it. For aesthetics, move the allocation into the common attach
code.

used for the boardinfo pointer to simply 'board'.

staging: comedi: adl_pci9118: use 'context' in (*auto_attach)
The pci_device_id 'driver_data' is passed as the 'context' when the (*auto_attach)
mechanism is used to attach this driver. Add a boardid enum and index the boardinfo
so that the "pci9118dg" boardinfo is automatically selected. This allow removing
the pci9118_find_boardinfo() helper.
Unfortunately all the boards supported by this driver have the same device id.
Add commented out entries in the device table for them.

The minimum convert time 'ai_ns_min' is based on the sampling rate of the A/D
