Rework the regulator handling of the ad7887 driver to match more closely what we
do for other drivers. Only request the regulator if a external reference is
used, but treat it as an error if requesting the regulator fails. Also remove
the possibility to specify the reference voltage via platform data and always
use the regulator for this.

We know that the sample buffer will at most need to hold two 16 bit samples and
the 64 bit aligned 64 bit timestamp. Preallocate a buffer large enough to hold
this instead of allocating and freeing it each time a sample is read.

The ADIS1360 and ADIS13605 are very similar and do have the same software
interface. The only difference is the contents of the PROD_ID register. Since we
now read the product id from the device name instead of the chip_info struct we
can use the same chip_table entry for both the ADIS1360 and ADIS13605.

The product id check currently ANDs the read id with 0xF000 and compares the
result to the product id from the chip info. Since none of the product ids in
the chip info table end in 0x000 the check will always fail. Furthermore it is
also wrong, the product id in the PROD_ID register will always match the part
number of the device.

Some of the ADIS16XXX devices are identical from a software point of
view with the product id register having a different content. If we keep the
current scheme of storing the product id in the chip info table this would
require us to have multiple almost identical chip info table entries. So instead
this patch changes the code to parse the product id from the device name.

Setting the sampling frequency for the adis16334 differs from the other devices.
This patch introduces two new callback functions to the adis16400 chip_info
struct which are used to specify how to read and write the current sample rate.
The patch also introduces the proper implementations for these callbacks for the
adis16334.

Related to this is that the adis16334 has no slow mode and so we do not limit
the SPI clock rate to 300kHz during initialization. The patch adds a new flag
for devices which do have a slow mode.

Support auto-attachment of supported PCI devices by adding the
`auto_attach()` hook (`pci9118_auto_attach()`) to the `struct
comedi_driver`.  This is called via `comedi_pci_auto_attach()` at PCI
probe time.

Previously, the driver's call to `comedi_pci_auto_config()` would fall
back to the old method of auto-attaching devices and would fail because
it couldn't find a board name matching the driver name.  The new method
doesn't care about that.

There are still a few problems.  All the boards supported by this driver
have the same PCI vendor and device ID, so it will just pick the first
supported board type, "pci9118dg".  (Other supported board types have
different AI ranges or different AI speeds, but are otherwise the same.)
Also, manual attachment of devices allows several optional features to
be configured, such as use of an external multiplexord, specified
sample&hold delays and options to ignore certain hardware errors.  These
will all be set to defaults for auto-attached devices.  A future version
of the driver may address these issues via configurable device
attributes.

Split most of the functionality of the attach routine `pci9118_attach()`
into a new function `pci9118_common_attach()` that can be called when
auto-attachment of devices is supported.  Move the enabling of the PCI
device and its i/o regions into this function.  Do the requesting of the
interrupt near the end of the function so it doesn't get enabled before
the device is ready.

Note that auto-attachment of PCI devices is currently broken in this
driver because the list of board names referred to by the `struct
comedi_driver` does not contain a "wildcard" entry matching the comedi
driver name.  This won't be a problem once support for the
`auto_attach()` method is added.

Also, rename addi_find_boardinfo() so it has namespace associated
