tc35815: Use generic PHY layer
Convert the tc35815 driver to use the generic PHY layer in drivers/net/phy. Also rename 'boardtype' to 'chiptype' which hould be more appropriate. Signed-off-by: Atsushi Nemoto <anemo@mba.ocn.ne.jp> Signed-off-by: Jeff Garzik <jgarzik@redhat.com>

-/* Auto negotiation. The scheme is very simple. We have a timer routine
- * that keeps watching the auto negotiation process as it progresses.
- * The DP83840 is first told to start doing it's thing, we set up the time
- * and place the timer state machine in it's initial state.
- *
- * Here the timer peeks at the DP83840 status registers at each click to see
- * if the auto negotiation has completed, we assume here that the DP83840 PHY
- * will time out at some point and just tell us what (didn't) happen. For
- * complete coverage we only allow so many of the ticks at this level to run,
- * when this has expired we print a warning message and try another strategy.
- * This "other" strategy is to force the interface into various speed/duplex
- * configurations and we stop when we see a link-up condition before the
- * maximum number of "peek" ticks have occurred.
- *
- * Once a valid link status has been detected we configure the BigMAC and
- * the rest of the Happy Meal to speak the most efficient protocol we could
- * get a clean link for. The priority for link configurations, highest first
- * is:
- * 100 Base-T Full Duplex
- * 100 Base-T Half Duplex
- * 10 Base-T Full Duplex
- * 10 Base-T Half Duplex
- *
- * We start a new timer now, after a successful auto negotiation status has
- * been detected. This timer just waits for the link-up bit to get set in
- * the BMCR of the DP83840. When this occurs we print a kernel log message
- * describing the link type in use and the fact that it is up.
- *
- * If a fatal error of some sort is signalled and detected in the interrupt
- * service routine, and the chip is reset, or the link is ifconfig'd down
- * and then back up, this entire process repeats itself all over again.
