de2104x: fix TP link detection
Compex FreedomLine 32 PnP-PCI2 cards have only TP and BNC connectors but the SROM contains AUI port too. When TP loses link, the driver switches to non-existing AUI port (which reports that carrier is always present). Connecting TP back generates LinkPass interrupt but de_media_interrupt() is broken - it only updates the link state of currently connected media, ignoring the fact that LinkPass and LinkFail bits of MacStatus register belong to the TP port only (the chip documentation says that). This patch changes de_media_interrupt() to switch media to TP when link goes up (and media type is not locked) and also to update the link state only when the TP port is used. Also the NonselPortActive (and also SelPortActive) bits of SIAStatus register need to be cleared (by writing 1) after reading or they're useless.
