Log Message:
More changes to prep port:
1) Add the NVRAM device.  This device allows us to speak with the nvram on
prep-based machines and read/write to it.  Also add a simple IOCTL
interface for speaking with the nvram from userland.  This hasn't been
tested yet, but eventually I plan to support it with the sparc eeprom
command.
2) Change the root device detection to use the nvram device to attempt to
guess the boot device.  Most machines should now correctly guess thier
boot device, though I expect a few devices to still not work quite right yet.
3) change the default IRQ to level rather than edge in the pnpbus if the
flags are invalid or empty. (based on output from a PowerStack E1)
4) correctly handle older machines in pnpbus that have FixedIOPorts
rather than variable ones.

Still have much to do.
