At some point, Measurement Computing / ComputerBoards redesigned the
PCI-DIO48H to use a PLX PCI interface chip instead of an AMCC chip.
This meant they had to put their hardware registers in the PCI BAR 2
region instead of PCI BAR 1. Unfortunately, they kept the same PCI
device ID for the new design. This means the driver recognizes the
newer cards, but doesn't work (and is likely to screw up the local
configuration registers of the PLX chip) because it's using the wrong
region.
Since the PCI subvendor and subdevice IDs were both zero on the old
design, but are the same as the vendor and device on the new design, we
can tell the old design and new design apart easily enough. Split the
existing entry for the PCI-DIO48H in `pci_8255_boards[]` into two new
entries, referenced by different entries in the PCI device ID table
`pci_8255_pci_table[]`. Use the same board name for both entries.

I broke `s626_set_dac()` by changing the type of the `dacdata` parameter
from `short` to `unsigned short`. It's actually designed to take a
signed value in the range -0x1fff to +0x2000 although values above
0x1fff get clamped to 0x1fff. (We could change the `maxdata` value to
0x1ffe to avoid the clamping, but `maxdata` values are usually a power
of 2 minus 1.) The bug results in all negative values passed to the
function being changed to +0x1fff by the clamp. Change the parameter
type to `int16_t` to fix the problem.

The 'IndxSrc' value for the standardized encoder setup is currently 1
bit wide and takes one of the following values:
S626_INDXSRC_HARD = 0 // index source from hardware encoder
S626_INDXSRC_SOFT = 1 // index source software controlled by IndxPol
However the hardware 'IndxSrcA' and 'IndxSrcB' values for the 'A' and
'B' counters are 2 bits wide. The above standardized values 0 and 1
correspond to the hardware values 0 and 2.
In order to simplify conversions between the standardized values and
hardware values, expand the range of standardized values to cover all
four possible values. The new values are as follows:
S626_INDXSRC_ENCODER = 0 // index source from hardware encoder
S626_INDXSRC_DIGIN = 1 // index source from digital inputs
S626_INDXSRC_SOFT = 2 // index source s/w controlled by IndxPol
S626_INDXSRC_DISABLED = 2 // index source disabled
(Note the change in value for `S626_INDXSRC_SOFT` and the replacement of

When setting up an encoder channel, the setup value includes a polarity
and direction, but these are the same bit of the setup value:
S626_CLKPOL_POS = S626_CNTDIR_UP = 0
S626_CLKPOL_NEG = S626_CNTDIR_DOWN = 1
In the construction of the setup value, both the CLKPOL and the CNTDIR
constants are shifted by the same amount `S626_BF_CLKPOL`. Only the
following combinations are set up currently (this may change if user
configuration of the encoder is implemented properly):
(S626_CLKPOL_POS << S626_BF_CLKPOL)
(S626_CLKPOL_POS << S626_BF_CLKPOL) |
(S626_CNTDIR_UP << S626_BF_CLKPOL)
(S626_CLKPOL_POS << S626_BF_CLKPOL) |
(S626_CNTDIR_DOWN << S626_BF_CLKPOL)
The first two are used in "counter" mode and is equivalent to:
(S626_CLKPOL_POS << S626_BF_CLKPOL)
The last one is used in "timer" mode and is equivalent to:
(S626_CNTDIR_DOWN << S626_BF_CLKPOL)
Use the shorter equivalents. The comments in "s626.h" indicate that the
'CLKPOL' constants make more sense for the "counter" mode (when the
encoders operate as up/down counters) and the 'CNTDIR' constants make
more sense for the "timer" mode.
