Set media to IFM_NONE if link is not up instead of the previous value.

addition of SerDes support. According to the docs, the 5706C and 5708C
phys are supposed to use the same MII model that is separate from the
SerDes parts, but the 5706C actually uses the MII model of the SerDes
parts. To fix this, readd the old 5706C entry to miidevs and add a
special check in brgphy_probe() for phys that match the 5706C ID. If
the phy is supported by the gentbi(4) driver, then it's a SerDes phy, so
we fail the probe and let gentbi(4) grab it. Otherwise, it's a 5706C phy,
so we let brgphy(4) grab it.

- Set/clear jumbo frame configurations for bge(4).
- Re-add BCM5750 PHY workaround for bce(4), which was mistakenly removed
from the previous commit.
- Move some PHY bug detections from brgphy.c to if_bge.c.
- Do not penalize working PHYs.
- Re-arrange bge_flags roughly by their categories.
- Fix minor style(9) nits.

mii_phy_match() API and takes care of the PHY device probe based on
the struct mii_phydesc array and the match return value provided.
Convert PHY drivers to take advantage of mii_phy_dev_probe(),
converting drivers to provide a mii_phydesc table in the first
place where necessary.

2) rework link state detection code & use it in POLLING mode
3) fix 2 bugs in link state detection code:
a) driver unable to detect link loss on bcm5721
b) on bcm570x chips (tested on bcm5700 bcm5701 bcm5702) driver fails
to detect link loss with probability 1/6 (solved in brgphy.c)
Devices working in TBI mode should not be affected by this change.

so the Broadcom Linux driver was used for clues to what these chips
support. It turns out they are similar to the 5705 with the 5751
being the PCI-Express version and needing special work-arounds and
settings.

These are 10/100 only NICs found on the IBM Thinkpad R40E and
G40. These seem to be based on the BCM5705 MAC but with a PHY
that doesn't support 1000Mbps modes.

- 5705 doesn't support jumbo frames
- Statistics must be read from registers
- RX return ring must be capped at 512 entries
- Omit initialization of certain device blocks
- Acknowledge link change interrupts by setting the 'link changed'
bit in the status register (used to have no effect)
- Remember to toggle the MI completion bit too
- Set the mbuf low watermark differently (on-chip memory buffers,
not BSD mbufs)
- Don't enable Ethernet@WireSpeed feature for certain 5705 chip revs
- Add additional PCI IDs for 5705 and 5782 parts
- Add a forgotten 5704 PCI ID
Most changes ripped kicking and screaming from the Broadcom linux driver.

- Disable AUTOPOLL when accessing the PHY as it may cause PCI errors.

- Check the UPDATED bit in the status block so the driver knows
that the status block as indeed changed since the last access.
Broadcom documentation states drivers should unset the UPDATED/CHANGED
bits after reading them.
- When changing media types, first loop the phy then set the media.
Broadcom documentation and Linux drivers do this and I observed
much better handling of link after this change.
- Broadcom documentation states that for 1000BaseT operation,
autonegotiation must be enabled. Fix hard coding of media so that
the driver only advertises 1000BaseT as the supported media type
and enable autonegotition.
- Only set Master/Slave on the 5701.
