Add an extern decl of try_bootp variable here since MD sources could set it.

In device_register(), check booted devices more properly:
- check "tlp" name on netboot
- use ata channel and drive numbers to check wd unit

Assume netboot if "nfsroot=/path" is specified in bootstring.

Use PCI bus/dev/function numbers rather than device unit
to check first tlp in device_register().

Add support for netboot via tlp0 with standalone tlp(4) driver
taken from arch/sandpoint/stand/netboot.
There are still some kludge but it just works on RaQ and RaQ2.

Fix my stupid bug in cache flush code and remove one kludge for it.

- use chaned mode for RX descs and allocate only one desc per each cacheline
  to avoid possible race condition between CPU writeback vs DMA write
- remove unnecessary FS and LS bits from RxD->xd0
  (sys/dev/ic/tulipvar.h sets them but maybe they are ignored?)
