More Broadcom BCM5705 updates

[Bill Paul]

I have merged in some additional updates provided by Paul Saab:

- Support the BCM5782 chip (5705 workalike, new PCI ID)
- Increase firmware handshake timeout
- Always check for GMII PHYs at PHY address 1 (required for
  some chips, doesn't hurt on the others)
- Add ASIC rev numbers for 5705_A1, 5705_A2 and 5705_A3

There may be some additional performance tweaks needed, but this should
get the device attached and working. As before, download the new code
from:

http://www.freebsd.org/~wpaul/Broadcom/5705

- Copy if_bge.c and if_bgereg.h to /sys/dev/bge
- Copy miidevs and brgphy.c to /sys/dev/mii
- Rebuild your kernel and/or if_bge.ko and miibus.ko modules
