NB: I have no idea what frequency the GIO SCSI cards use. We'll have to
re-investigate this if we ever come across one.

Provide attaching hpc devices with the eeprom contents, should a chip be
connected to the HPC. The only real reason for doing this is to get the
mac addresses off of E++ ethernet boards and the Challenge S IOPLUS board.
If no eeprom is present, we read in invalid data and take some default
action (query ARCBIOS).

Fixes to HPC abstraction layer from Steve Rumble:

- hpc1_hdd_{ctl,bufptr} and hpc3_hdd_{ctl,bufptr} are
established in hpcreg.h. All references to these fields
are updated with the exception of if_sq: (haltwo,
hpcdma). This makes reading the code and spotting bugs
easier.
- hpcdma.c was applying EOCHAIN to the wrong descriptor
word for the hpc1 case.
- I added scsi_max_xfer to the abstraction layer, and it
allows some crusty #defines in wdsc.c to be removed.
hpc1 now doesn't waste descriptors as it once did.
- hpcreg.h was updated to reflect the lack of XMITDONE
bit in hpc1. HPC1_REV15 added for a test in hpc.c
- hpc.c now verifies HPC1 revisions (1.0 vs 1.5) and
prints the output a little prettier ;)
- power interrupts shouldn't establish on non-IP22
platforms.

Introduce abstraction layer for HPC registers and values, which addresses the
divergence between HPC revision 1.5 and revision 3.

The wdsc driver has been updated to reflect this layer (and may now work on
IP20). The sq driver needs a bit more work before it can be committed.

Add dpclock driver (and minimal hpc1 goo) for ip20.

Replace lots of 8x<space> with <tabs> and other miscellaneous indentation
fixes.
Wrap a couple of long lines.
Use <return-type>\n<function name> as per KNF in a few places.

Initial implementation of WD33C9x SCSI driver for SGI IP22 platforms.

Based on mvme68k and Atari drivers for the same chipset with the
addition of bus_space support. Attempts have been made to seperate out the
machine dependent dma components and more work is required in this area.

Tested on SGI R4K Indy, but has little testing on other platforms.
