Move aic7xxx register definitions to sys/dev/aic7xxx/aic7xxx_reg.h.

Browse Source 
Start the revamp of the initialiation process.  New routines include
ahc_alloc, ahc_free, and ahc_reset.  These help divide the work of staring
up a board more logically between probe and attach.

ahcintr now takes a (void *) and returns int.  The pci code uses it directly.
Until the PCI code for shared edged triggered interrupts is removed, the
eisa code uses a stub (ahc_eisa_intr) that throws away the int returned
by ahcintr.

Use MHz instead of MB/s for printing out sync rates.

Print out "aic7880" instead of "aic7870" for the new aic7880 chips.

* Serial EEPROM Control (p. 4-92 in 7870 Databook)
* Controls the reading and writing of an external serial 1-bit

* first set the SEEMS bit that generates a request to the memory
* port for access to the serial EEPROM device. When the memory
* port is not busy servicing another request, it reconfigures
* to allow access to the serial EEPROM. When this happens, SEERDY
* gets set high to verify that the memory port access has been
* granted.
*
* After successful arbitration for the memory port, the SEECS bit of
* the SEECTL register is connected to the chip select. The SEECK,
* SEEDO, and SEEDI are connected to the clock, data out, and data in
* lines respectively. The SEERDY bit of SEECTL is useful in that it
* gives us an 800 nsec timer. After a write to the SEECTL register,
* the SEERDY goes high 800 nsec later. The one exception to this is
* when we first request access to the memory port. The SEERDY goes
* high to signify that access has been granted and, for this case, has
